How can I fire a trigger script base and a field change

 

Before triggers existed,  I used plugin ZippScript,   in a calc field  that called a script

 

Thanks R

Hi Rod from my home down,

 

FM triggers can't fire based upon calculations so you will need to instead trigger the action which changes the calculation.  Can you provide more specifics on the data change which would trigger it?

On object modify script trigger? Not sure what else you mean unless you want to fire a script based on the value in the field in which case use on modify to fire a script to evaluate field contents and continue or not.
