Hi, and thanks in advance for any help!

I'm trying to basically replace the selection box on a PivotTable, i.e. the box with the check marks you get when you click the down arrow on a PivotField. Essentially, I want to trap the mouse click on the arrow for the PivotField and display my own UserForm. I'm hoping this is somehow possible, although it seems like it might be a struggle.

Will this require API calls? I have almost no experience with API calls, so any help or a reference to get me started would be appreciated as well.

Thanks again!

Edit: I'm using Excel 2003 under Windows XP Pro.
