MV,

Have you tried protecting the sheet? Format the cells that you want them to use as unlocked, then protect the sheet to prevent row
and/or column deletions.

If they should be able to delete some rows or columns, then you'll have to write utilities that unprotect the sheet, do the
deletion, then reprotect the sheet.

HTH,
Bernie
