Hello,
I am having a crystal report using datastored in a dataset. When I select one of items in a dropdownlist, it gives me this error message. Note that I used that code before in another web page using a different crystal report and a different dataSet and it worked successfully, but this time it doesn't work...anyone can tell me what causes this error and how to solve it?
NOTE: I am using a vb code behind in my .aspx page
