Match spec error: Could not find type: "sdate"

[dqm]

I have a problem with a match spec I'm writing.
When I try to test a pass, I get the following error:

##E IIS-DSEE-TOSH-00003 14:43:03(007) <main_program> Syntax error: Error in "QSund_std" operator: Error in output redirection: Error in output parameters: Error in modify adapter: Error in binding: Could not find type: "sdate", line 44
Expected operator name, got: ")", line 63; text: QSund_std

I have a date field in the input structure. This error occurs regardless of whether it is used in a pass or not. It's the DoB, so I can't do without it.

This is the first real attempt we have made at matching on this site. A basic test was done, but not using date fields.

Any help would be appreciated.
