You are correct that I have think you have Bids 2008 and SSRS 2012.
I have the following additional question which is:
Would you tell me what the difference between the following 2 statements are:
1. IIF(Globals!RenderFormat.IsInteractive, False, True) and
2. =IIF(Globals!RenderFormat.Name = "RPL", true, false)
Note: I can not get the columns to hide when I use the code
"=IIF(Globals!RenderFormat.Name = "RPL", true, false)"
Can you tell me why one works and the other format does not work?
