calling print preview from a code loop

[DBAchick]

I am using a form with a number of checkboxes on it. After a user checks some boxes and clicks a button to print, the code should read all the checked boxes and loop through them to get a report name. The loop calls each report in turn and print previews it. Unfortunately, the code opens all the reports one after the other on top of each other. How can I make each print preview come up one at a time until it is closed then open the next one.
thanks in advance
