Hi David,

in principle Bob is correct, some more details would be helpful. But
there are some general points that can be made:
- selection fields etc. which offer the exact answers to requred
variables are a great aid
- all entry fields which can/should be modified by the users can be
surrounded by a coloured background and adjusted by supportive comments

Your question suggests, that your Excel sheet is used to generate
reports from another source. Then, the a.m. entries in selection fields
can be used in the specific query code.

Hope this was of some help for you
Udo
