I'm missing something. I did the changes you suggested and I get an error when I click on a check box.

Script error : unknown command
If $var.Value = 0

If it's not to much trouble could please explain the use of the () in a function call?

Here is how my script looks.
code:
 $Form = CreateObject("Kixtart.Form")
 
$Form.Caption			= "Insatll Stuff"
$Form.ScaleHeight		= 300
$Form.ScaleWidth		= 250
$Form.FontName			= "Arial"
$Form.FontSize			= 9
$Form.Center

$Topdistance = 20
$nul = open(1,test.dat,2)
$var = readline(1)

do
$=execute(' $$$var = $$form.CheckBox("$var") ') 
$=execute(" $$$var.Left= 10")
$=execute(" $$$var.TabStop= 0")
$=execute(" $$$var.Top= $Topdistance")
$=execute(' $$$var.OnClick= "chkAccountDisabled_Click($$var)"')
$=execute(" $$$var.Enabled= 1")
$=execute(" $$$var.Value= 1")
$Topdistance = $topdistance + 20
$var = readline(1)
until $var = ""
$=close(1)

$cmdExit	 		= $form.CommandButton("Install!")
$cmdExit.FontSize		= 12
$cmdExit.FontBold		= 1
$cmdExit.Top			= 250
$cmdExit.Width			= 100
$cmdExit.Left			= 75
$cmdExit.OnClick		= "Return_to_script()"

$Form.Show


While $quit <> 1 and $Form.Visible 
$=Execute($Form.DoEvents)
Loop
 


Function chkAccountDisabled_Click($var)

    If $var.Value = 0
	
	? "$var Checkbox was not checked"
 
    Else
 
	? "$var Checkbox was checked"
 
    EndIf
EndFunction
Thanks
