Hate to do this, but can you post the form, or a screenshot of the designer window with the form layout and heirarchy, as well as the current checkbox script?

Which checkbox is your code in?  Normally you don't have to explicitly set/clear the checkbox that you're clicking, it will automatically toggle. 

Oh well, thought it might be an easy one...Are the other objects (hc1, etc) checkboxes?  I'm not familiar with the "value.integer.value" syntax; I usually set them with "hc1.rawValue = 1" and reset with "hc1.rawValue = 0".

For starters, there is a comma instead of a period on the two marked lines:if  (this.rawValue == 0){     hc1.value.integer.value=0;     hc2.value.integer.value=0;     hc3.value.integer.value=0;     hcgray.presence = "hidden";     sfrhc1,value.integer.value=1;     sfrhc2.value.integer.value=1;     sf...

Does each page have its own table (Tables_P2, etc) or is it all one big table?

You're right, creating a form like this is a pain in the butt.  It's all about trade-offs.  The usual idea when creating forms is to make the user's life easier.  Having to teach every user how to enable a toolbar and create an oval when most people who open PDFs don't usually use that feature is a ...

As a follow-up, I had said I would try to put together an example for you.  The setting of the change indications and the highlighting of the fields is not a problem, but I did have an issue that perhaps one of the experts on the forum can help with:The problem is how to detect a change in a text fi...

Objects have a "somExpression" property on them.  For example, in javascript you can use:    var exp = this.somExpression;

Sorry, no simple switch-like statement in FormCalc, although there are convoluted ways to simulate it.  For your example the easiest is if/then/else:if (xfa.event.newText == "A - Approved") then     form1.Page1.TextField1.presence = "visible"     form1.Page1.TextField2.presence = "visible"else     f...

I have a working example that is similar to your layout.  Let me know where to send it to.
