I have a linked procedure class and SQL gateway setup and I can't seem to get any response, status or error from using the stored procedure, I think it must be something big I'm missing to not even get a status.

Can someone see what my problem is please, any help would be very much appreciated.

Class generated by linked procedure wizard:

Include %occInclude /// 
Class dbo.MrnLookup [ Not ProcedureBlock ]
{ ClassMethod MrnLookup(pp01 As %String(MAXLEN=8), ByRef mrn As %String(MAXLEN=20)) As %Integer [ ProcedureBlock = 1, ReturnResultsets, SqlName = MrnLookup, SqlProc ]
{
