How to disable(greyedout) a checkbox from some action in the back-end

[Guest_imported]

I am working on data manupulation (Access Database) using ASP. I want a single or some checkboxes to be greyed out in the client side depending on some action in the back-end. Please help me as to how to do that. Like, I have:
if((glasstaken)=0)then
response.write "document.form1.ch[3].disabled=true"
but it doesn't work. So, how to pass this info to disable that check box in the front end. Thanks in advance!

As you build your output HTML to go back to the client simply create it as:

<INPUT id=checkbox3 disabled 
type=checkbox name=checkbox3>

... of course inserting your conditional logic.
