Please could someone help me on this issue?
I have a VB.Net 2008 Application that I have already created it's setup. When I installed it on another PC (Apart from my Develoopment PC) I have this issue with viewing the reports. There are couple of reports created with the CR within VS. The reports are showing as they should but the Total count, Total Sum for some of the reports are not showing. What is wrong with my reports or application. FYI - I have put in the prerequisites: .Net Framework 3.0, Windows Installer 3.1 and the CR Basics for VS 2008 (x86, x64), I have also tried to add in MS VS 2008 Report Viewer to try the work around but still the same problem. What is wrong with my report or application? Please need urgent help on this.
