Does it display correctly from within Crystal?
How are you accessing it through the viewer?

I suspect you have duplicated a line in your ASP code.
Can you post the relevant portions of the ASP? Howard Hammerman,

i doubt this is the problem bacause i use the same website to output another very similar form and i don't get the same problem. any other ideas??
do you think it could be the version of active x viewer that i am using activexviewer.cab#Version=8,0,0,224 ?
