weapon = guiCreateGridList(320, 173, 218, 344, false) 
        guiSetVisible(weapon, false) 
        closed = guiCreateButton(165, 321, 56, 22, "", false, weapon) 
        comprar = guiCreateButton(0, 320, 52, 23, "", false, weapon) 
        guiSetAlpha(closed, 0)  
guiSetAlpha(comprar, 0) 
        guiGridListAddColumn(weapon, "Weapon list", 0.3) 
        guiGridListAddColumn(weapon, "Municion", 0.3) 
        guiGridListAddColumn(weapon, "Price $", 0.3) 
      for i = 1, 18 do 
            guiGridListAddRow(weapon) 
        end 
        guiGridListSetItemText(weapon, 0, 1, "Pistol", false, false) 
        guiGridListSetItemText(weapon, 0, 2, "-", false, false) 
        guiGridListSetItemText(weapon, 0, 3, "400 $", false, false)

function drawOnRowClick()

I does not work

[Castillo]

function drawOnRowClick() 
    row = guiGridListGetSelectedItem() 
    name = guiGridListGetItemText(weapon, row, 1) 
    if (name) then 
        addEventHandler("onClientRender", root, draw1) 
    end 
end 
addEventHandler("onClientGUIClick", weapon, drawOnRowClick) 

Missing "weapon" ( grid list ) at guiGridListGetSelectedItem.

[Jacobob14]

function drawOnRowClick() 
local row = guiGridListGetSelectedItem ( weapon ) 
   if ( row == 0 ) then 
        addEventHandler("onClientRender", root, draw1) 
   elseif ( row == 1 ) then 
        addEventHandler("onClientRender", root, draw2) 
    end 
end 
addEventHandler("onClientGUIClick", weapon, drawOnRowClick) 

I did not if it will be fine

function drawOnRowClick() 
local row = guiGridListGetSelectedItem ( weapon )

        addEventHandler("onClientRender", root, draw1) 
   elseif ( row == 1 ) then 
        addEventHandler("onClientRender", root, draw2) 
    end 
end

It will, but only in specific case. That's why your code shouldn't be used because it's dirty (duplication of code: draw1, draw2 ..; not removing event handler before adding another etc).

So please dont.
