Yesterday I found I had not set my Keyfield (RecordID) to Auto Increment
so I set a new field with phpMyAdmin called 'id'. And this is now
working fine and Auto incrementing. I deleted the old RecordID field.
Why did you do that ?
Why not just alter the existing Keyfield (RecordID) to autoincrement ?
I tried several times and the Auto Increment just reverted to 'NO' every time I saved it.

When you talk about the Keyfield, do you mean that this was a PRIMARY
KEY or was it a reference for other tables (FOREIGN KEY)?

Yes I mean the Primary Key - I have no Foreign Keys
Did you attribute PRIMARY KEY status to the new field that you created?
Did you recreate any references (FOREIGN KEYS) to other tables ?
I deleted the old Primary key and marked the new field as Primary

If you didn't, then by deleting your original RecordID field, you
probably deleted the primary key and/or any references as well, and in
all likelihood that is the reason why the forms that relied on that key
to be set no longer work.

In which case should I rather export my data out and start again?? My feeling is this might be the best and quickest way to go.

Thanks for the help.
