Action with a button doesn't work

[Ralxys]

Hi everyone,

Today, I would like to make a button which is able to be enabled only if the checkbox have been checked before.
This is my code (it not working):

local checkcl = vgui.Create( "DCheckBoxLabel", Panel )
checkcl:SetPos( 25, 265 )
checkcl:SetText( "I confirm that I am over 16 years of age" )
checkcl:SizeToContents()
function checkcl:GetChecked( var )
if ( IsValid(var)) then
Button:SetEnabled( true )
else
Button:SetEnabled( false )
end
end

local Button = vgui.Create( "DButton" , Panel)
Button:SetPos(250, 295)
Button:SetSize( 100, 50 )
Button:SetText( "Validate" )
Button.Paint = function( self, w, h )
draw.RoundedBox( 0, 0, 0, 0, 0, Color( 0, 0, 153, 250 ) )
end
Button.DoClick = function( )
Panel:Close()
end

Thanks.

Thanks Heroezzz, you save me.

But can you explain me why you use Think(), and what it mean ?

Thanks.

Just

function checkcl:GetChecked( var )

function takes only [U]true[/U] and [U]false[/U] and can not be used as a variable! because it only takes labor and Fals and could not be used for functions
аA function to think speaks for itself! She thinks! Just read it

Pretty hard to understand because I'm beginner. But I will continue in aim to better understand.

If I understood correctly, you will mean that the thing that I want to do need to have Think because this function have a choice True or False. But is the function can work without Think ?

The function is often used to think, but you need to know what features are valid values ​​if, else, else if
