Records not deleted. Data read only

[Mario]

When I tried to delete a record, I get this message: "Records not deleted.
Data read only"

When I tried to delete a record, I get this message:
"Records not deleted. Data read only"

I assume this is happening in a query, so see:
Why is my query read-only?

How are you trying to delete the records? Do you get a Read Only message when
starting the database? Can more than one person be using the database at a
time?

I had a group by clause. Took it out and it worked.

Thank you for your time.
