I have a parameter query that prompts for criteria each time it's run (such as [enter the date] or [enter the unit number]. After awhile, the prompt comes up once, I enter the data and then the prompt comes up a second time. I enter the data and the query executes. If I delete the field with the prompt creteria and add it back in, it works as it should. However, after awhile, it starts the double prompt.
