Open Manage | Database | Fields
Find and double click the project number field
You'll find a box for this that you can edit on the auto-enter tab.
I've tried a few variations under the auto-enter tab, but it doesn't seem to work. Can you recommend which option?
Without being able to see your database, I am making guesses as to how this field was set up. The most likely way is that the field is defined on the auto-enter tab to auto-enter a serial number. If it is so defined, you can edit the next value box and then the next new record that you create in this table will auto-enter the value you enter in this box.
But it is possible that something more sophisticated was set up for your field--it may even use a script to enter the next value.
This is the screen. Do I need to choose something different?
