Hi
I have built out a process builder flow that triggers when a task is created and meets criteria. 




It will then follow to update a custom field Dials on related object Opportunities that is defaulted as "0" to increment +1 if criteria met.

I successfully get the field to increment from 0 to 1 however cannot seem to get it to fire for 1 to 2.  

I cannot use formula Dials + 1, since it's pulling from the Task field.

Any ideas how I can get this cross object logic to increment from 1 to 2 and so forth?
