I spent a lot of time working on an alert profile action, going straight by the book before it dawned on me - The Helps are wrong!
Listed in the Helps: %ActResponseTime%
Should be: %AckResponseTime%
(That one should've jumped out at me. %@*! cut and paste! )
Value listed in helps: "not acknowledged"
Actual value: "Not acknowledged"
(the cap. "N" does make a difference when used in a formula)
I'm just trying to help out the next guy!
