I have an asp.net web page with a couple of regularexpresion validators on it. On my dev machine they work fine. The app code resides under the www root. When I move it to the test machine the code resides on a different drive than where IIS is installed. The app works fine, the validators just sort of work. The validators are associated with the validator summary control with an image to indicate the field with an error. The image shows the error, but the summary does not show the messagebox. Any suggestions?<BR><BR>Thanks in advance<BR>Thomas
