i am working on a c# 2005 web app with sql 2005. I created 5 buttons, 5 crystal reports. When i click on the buttons the report loads fine, however, when I click on any items on the crystal reports tool bar i always get the same error message "Unable to connect: incorrect log on parameters." If the logon parameters were incorrect, how are the reports working? The report viewer and report source must be dynamic so each report will work?  I have the book, Crystal Reports .NET Programming, but I'm not seeing a solution to my problem. Thank You.
