Detrmine How Many Rows are Frozen At Top Of Worksheet

I have macros that I use to update the data rows in a worksheet, but I need to determine how many rows (if any) have been frozen by the Freeze Pane option, so that I can skip these rows in the data update process. Currently I am sending an Input Box asking the user for the number of heading rows when they run the macro, I'd like to be able to put in the number of frozen rows as the default to this input box.
Thanks

Thanks VBA Noob.
That will work fine, I just need to establish position at the top of the sheet and then get the ScrollRow attribute to get the number of frozen rows. I was hoping that this value was in an attribute that I could just retrieve from the worksheet object without depending on the position in the spreadsheet.
