Version of the script
Look in the stored procedure, and it'll have a version date & number near the top. Put that in here. If it's not the current version (dated in the last month), then upgrade to the current version and test that before reporting a bug - we fix a lot of stuff in each new build. We'll flat out close bug reports for older builds.
