I have an app that keeps giving me the following error message and I want it to quit!!!!!

Run-time error '2501'
The OpenReport action was canceled.

I know why it is giving the error to me here goes:
I am using access as my backend. I created 1 query and 1 report in access. I am from my vb app printing the 1 report using the data from the 1 query. The query ask the user for information, simply a client number. However if I press cancel on the input box for the query I get this crazy error. Is there anyway and can just cancel it and be done with it!!

Thanks.
