One more Problem! About GuiGridList

[Hero192]

Any idea?

It sends me another errors other IDs working fine,but the first ID always gives this Error

ERROR: attempt to index field '?' (a nil value)

it says the error is in this line

      local weapPrice = Weapons[guiGridListGetSelectedItem (grid)][3] 

--Table of weapons:

Weapons = { 
{1,1,400}, 
{2,2,1500}, 
{5,5,550}, 
{6,6,700}, 
{7,7,850}, 
{8,8,1500}, 
{9,9,2000}, 
{10,10,800}, 
{12,12,800}, 
{15,15,500} 
}

you need to now that what trying to do is trigger { id, Price} for weapon and maybe contain {Ammo}

from The Client Side that contain { Table And Gridlist } well, What you Gone do is

Client Side First :- Create Table and insert { ID , Price , AMMO } like This

  
Weapons = { 
{ID,Price,AMMO} 
} 
  

Example

  
Weapons = { 
{32,"Name",100,9999} 
} 
  

after The Table Created Now you need to Create Gridlist Then insert The Table in the Gridlist

and Create Button for Triggering server function

  
        btnbuy = guiCreateButton(773, 596, 127, 41, "buyWep", false) 
        gridlist = guiCreateGridList(412, 179, 488, 412, false) 
        guiGridListAddColumn(gridlist, "#", 0.2) 
        guiGridListAddColumn(gridlist, "Name", 0.2) 
        guiGridListAddColumn(gridlist, "Price", 0.2) 
        guiGridListAddColumn(gridlist, "AMMO", 0.2)    
 for k,v in ipairs ( Weapons ) do 
            local row = guiGridListAddRow (gridlist) 
            guiGridListSetItemText (gridlist, row, 1,v [1] , false, false) 
            guiGridListSetItemText (gridlist, row, 2, v [2], false, false) 
            guiGridListSetItemText (gridlist, row, 3, v [3] , false, false) 
        guiGridListSetItemText (gridlist, row, 4, v [4] , false, false) 
        end  
function buygun() 
if (source == btnbuy) then  
    if (guiGridListGetSelectedItem (gridlist)) then 
      local weapID = guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 1) 
      local weapName = guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 2) 
      local weapPrice = guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 3) 
       local weapAMMO = guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 4) 
      triggerServerEvent ("buyweapon", getLocalPlayer(), weapID, weapName, weapPrice, weapAMMO) 
    end 
    end 
    end 
addEventHandler ("onClientGUIClick", getRootElement(), buygun)  
  

Server Side :-

addEvent ("createweap", true) 
addEventHandler ("buyweapon", getRootElement(),  
function(weapID, weapName, weapPrice, weapAMMO) 
  if (getPlayerMoney (source) >= tonumber(weapPrice)) then 
       takePlayerMoney (source, tonumber (weapPrice)) 
    giveWeapon(source,weapID,weapAMMO) 
  else 
    outputChatBox ("Have No Cash!", source, 255, 0, 0, false) 
  end 
end 
) 
  

i Hope you get the idea

for more information about the tables and gridlist

Any idea?

--Table in Client side:

Weapons = { 
{1,1,100}, 
{2,2,1500}, 
{3,3,1000}, 
{4,4,10000}, 
{5,5,122}, 
{6,6,1222} 
} 

Thanks for the ideas, look when i do this type for money table

        guiGridListSetItemText(gridList, row, 3, v[3].."$" , false, false) 

i get Error and the player being not able to take money

ERROR:server.lua:26:attempt to compare nil with number

Line 26 is in server side its the part of 26line

if (getPlayerMoney (source) >= tonumber(weapPrice)) then 
       takePlayerMoney (source, tonumber (weapPrice))

Of course. The dollar string at the end of your item text is not a number! This is already the second time you did this.

  
        btnbuy = guiCreateButton(773, 596, 127, 41, "buyWep", false) 
        gridlist = guiCreateGridList(412, 179, 488, 412, false) 
        guiGridListAddColumn(gridlist, "#", 0.2) 
        guiGridListAddColumn(gridlist, "Name", 0.2) 
        guiGridListAddColumn(gridlist, "Price", 0.2) 
        guiGridListAddColumn(gridlist, "AMMO", 0.2)   
 for k,v in ipairs ( Weapons ) do 
            local row = guiGridListAddRow (gridlist) 
            guiGridListSetItemText (gridlist, row, 1,v [1] , false, false) 
            guiGridListSetItemText (gridlist, row, 2, v [2], false, false) 
            guiGridListSetItemText (gridlist, row, 3, v [3].."$" , false, false) 
        guiGridListSetItemText (gridlist, row, 4, v [4] , false, false) 
        end  
function buygun() 
if (source == btnbuy) then 
    if (guiGridListGetSelectedItem (gridlist)) then 
      local weapID = guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 1) 
      local weapName = guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 2) 
      local weapPrice = tonumber(guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 3):gsub("$", "")) 
       local weapAMMO = guiGridListGetItemText (gridlist, guiGridListGetSelectedItem (gridlist), 4) 
      triggerServerEvent ("buyweapon", getLocalPlayer(), weapID, weapName, weapPrice, weapAMMO) 
    end 
    end 
    end 
addEventHandler ("onClientGUIClick", getRootElement(), buygun)

It's still doesn't works ,i mean it doesn't take player money@GTX it gives Error about tonumber

here's the message: bad argument #2 to 'tonumber' (base out of range)
