Hello DOJO

I am trying to use condition inside alarm template.
I fail to exclude/include alarm template line with regex.

The condition has to verify if the first column is : nn/empty (example '8/ ')

my regex is OK on http://regexstorm.net/tester, but doesn't work on  template

Alarm should be Critical if Enabled and 'nn/empty'

It works if I use "equal to" or "not equal to" but only for one line as expected

Do you think it's a syntax problem like separator format, or misconfiguration  ?
