BBWin and Message problems

Not sure if this is the right place...

I have a particular error in my logs. It's not a real issus unbless I see 10 of them in a 30 minute period, so I set up a rule in the msgs section...

<msgs> <setting name="summary" value="true" /> <match logfile="Application" eventid="3317" count="10" delay="30m" /> </msgs>

Is this syntax correct?
