crexport fee application - question on passing parameter

[hak-joni Cheung Hui]

Hi
 
This free tool is great and let me to run rpt file and export to pdf in email. However, when I am trying to run a rpt with a parameter (string type), it fails and saying Misc Error with this:
 
Discrete Parameter "@pSchedule" = "CY"
 
I have this parameter field called @pSchedule in SPROC. Is that @pSchedule should be used as parameter name as -A@pSchedule? or I should use the rpt pompting text "Please select the time range:"?
 
Or is the error coming from the parameter value "CY"?
 
Thanks so much!
