I tried that and still not working. However I set it to Dynamic. But if I go to File>Save As my only options to save are as static forms. I cannot figure out why. This is a form where there is an underlying image and the fields are on top of it, but I am not sure why that would matter.

I set it as Acrobat 7 (Dynamic) XML Form in both the File>Form Propertied>Defaults area and in Tools>Options>Document Handling and still have the same issue. My javascript code is:----- topmostSubform.Page1.Checkbox1::mouseUp: - (JavaScript, client) ---------------------if (Checkbox1.rawValue == 1) ...

I have this same problem. When the default is visible, it works. When the default is invisible it does not. I want the field to be invisible when the form is initially opened.
