>>>I've got a form with a pageframe on it. This pageframe contains a lot of pairs of text boxes, one for the last date and one for the next date. I set the value of nextdate based on the value from lastdate through a simple NextDate method.
>>>
>>>My problem is when the form refreshes, the nextdate textbox refresh() errs out. I've traced into it and found that "this" is a form instead of a textbox, so there is no "value" associated with it. The part that confuses me is that the form only errs out on the first nextdate textbox. All the others refresh fine.

>>>The refresh method contains code like the following
>>> If this.value = date()

Where is this code. If in the refresh method of the form then this.value is wrong referenecing. You need this.textbox.value etc.
