Hi Parra,
These boxes are popping up because the querries have criteria in them that can't be found, so they are requesting the value from you.
Say you have a select query, well you can set one of your criteria to something like [Forms]![FrmMain]![sfrmmain].[Form]![lst01] to have it filter the query on that field by [lst01].
Now if you move this query, and don't initiate it from the form containing the control [lst01], the query will not know what to use for this value, and prompt you with a pop-up.
You can also go to a query, and type in the criteria field something like:
[Enter Data] and when you run the query, a pop-up will appear saying:
Enter Data:
What you should do is find the query giving you trouble, open it in design view, and then look at all the criteria fields and see if there is one that has a criteria referring to a control you no longer have in this database, since you imported it from elsewhere, and relace this criteria with a control that is in this database.
edit: I see that you are not running the querries, only moving, though you still should get rid of the criteria if they refer to objects you no longer have. Also, if you click on the view icon, and set your query to design view before you open it, in other words, select the query icon, and then select the view icon and set to deesign view, you can keep Acces from trying to run the query, and go right into the design.
You also might have referenced fields that no longer exist.
HTH,
