When my user completes entry into the spreadsheet they press a button that
looks through all the cells and checks for certain error conditions (no
commas, must be numeric ...).
I would like to add a event that checks the value in the cell to the list of
values assigned to it. Most of my fileds have drop down lists (created as
lists) but not all so I would need to be find out if the list exists for the
cell and then if the cell value is valid.
Most of my issues around this are from the users pasting values into the
cells and bypassing the list validation.

Thanks in advance for any help. This group has been very helpful
