[rt-users] How to detect a custom field change in a scrip

[lobo+rt at mental.com]

Kenn,

() Do you REALLY care what the old value was? We use Custom Fields as triggers
() on a lot of scrips, but we really don't care what it used to be. We only
() care that it has changed and what it has changed to. It makes the code
() easier to write and debug.

yes, I only care about the new value and that it actually has
changed, sorry for not being more clear.  

Your mail made me search for "trigger", and that lead me to

which looks as if tells me all I need.  Thank you very much!

    Ciao, Lobo
