Ok my research has led me to believe there is a version compatibility issue going on here. Someone posted this in another forum who had the same issue
Crystal Report Formula giving error in ASP.Net Website : The Official Forums for Microsoft ASP.NET
"Well the problem was that the version of CrystalDecision libraries i was using was "10.5.3700.0" . However , i had the latest version as well. When i changed the libraries to "14.0.2000.0" everything started working fine."
I am currently using CR 2008 to build the reports but using VS 2008 to deploy via web. How do I proceed from here? I am not sure how this person was able to achieve this as some websites are saying it's not possible.
Thanks,
AB
