Referring to a GUI element in another form

I have a program with 2 forms. When attempting to get the status of a
checkbox in the sub-form by referring to it in the main form, I'm
getting an 'identifier not found' error, even though I have added the
sub-form's unit to the 'uses' list.

Any idea what I'm missing? Thanks.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
form2.checkbox1
assuming the form name is form2 and checkbox1 is the check box name

On a side note:
  Using good OOP practise, I recommend you define a Public property on
"form2" that checks and returns the value of the UI component. Never
hard-code component names like than into you application/business
logic. Just my 2c.
