Entry level question about adding custom rules. Snort won't start w/ rule.

I installed and setup snort Security 22.214.171.124 for my wan interface to just log alerts not blocking.
I enabled the categories for the gpl2 list.
So I went to custom rules drop down and adding the following:
alert tcp any any -> any any ( msg:”DAT”; )
When I add this snort stops working and I can start the process, but when i enable the interface it kills snort again.
My alert may not be the correct syntax, but looking at a snort page on alerts it appears to be correct.
Anyone with experience think I just have bad syntax or did I add a custom rule in the wrong place or this could be an issue with the version of snort package I am running?

Your rule syntax is missing the CLASSIFICATION tag (uses the classtype keyword). The Snort binary on pfSense wants that in a rule because of some customization done in the CSV output module. If that section of the rule is missing, it causes problems.
