Help with gui edit

[xXMADEXx]

Hey guys, im trying to make my edit only allow numbers 0-9, but not really any luck. The text to show that you're only allowed to use 0-9 will work, but it won't cancel the event.

addEventHandler("onClientGUIChanged",root, 
    function () 
        if source == rog_modshop_colors_edit_red then 
            local t = tonumber(guiGetText(rog_modshop_colors_edit_red)) 
            if (t=="1") then else outputChatBox("Modshop: You are only allowed to use 3 characters, of 0-9",255,0,0) cancelEvent() end 
        end 
    end 
)

Your code is weird. You are checking a string against an integer, which is not possible. And you are also forgetting to check the values in case they are strings or less/more than 0-9.

Client-side

addEventHandler("onClientGUIChanged", root, 
    function() 
        if source == rog_modshop_colors_edit_red then 
            local t = tonumber(guiGetText(rog_modshop_colors_edit_red)) 
            if t then 
                if (not t >= 0) and (not t <= 9) then 
                    outputChatBox("Modshop: You are only allowed to use 3 characters, of 0-9.", 255, 0, 0, false) 
                end 
            else 
                outputChatBox("Modshop: You are only allowed to use 3 characters, of 0-9.", 255, 0, 0, false) 
            end 
        end 
    end 
)

cancelEvent doesn't work for that event.

Replace your entire code with

guiSetProperty(rog_modshop_colors_edit_red,'ValidationString','[0-9]?[0-9]?[0-9]?|')
