Why cannot Calc SaveAs Excel when "Validity" commands are involved?

I use “Validity” extensively. When “Validity” is used, the spreadsheet fails saving into Excel formats. A friend of mine who is a programmer at Microsoft for their Office product set telss me that the Range Nasme is not being properly converted to Excel format. Is there a “fix” on the horizon?

Supposedly you should check the bug report that you’ve filed from time to time to find it out?

OK, after more effort than I had imagined, it turns out that using Cell Ranges rather than Range Names solved my problem. It seems somewhat strange, but it worked**!**
