Limit the amount of values in a value list.

[Alex France]

I have a drop-down list which users can edit and enter more values but I want to limit them to entering no more than 6 different values. Is there anyway I can limit the value list to having a maximum of 6 seperate values.

I want to do this so that if users want to enter more than 6 values then they can pay for a slightly higher priced edition of the database.

Any help is very welcome, sorry if I didn't explain very clearly.

Perhaps you could create a related table that contains 6 records and a field which will be referenced in the Value List. Set the Privileges for this table to 'Read' and 'Edit' but not 'Create' or 'Delete'.
