I"m trying to put a validation rule in place that requests the "Next Step: to be filled if the Stage is changed. Currently the validation rule below works and ignores the request if the stage is set to closed lost, but it is not working for Closed Won.
For Clarity: If the stage name is changed please update the "Next Step" field, however if the Stage Name is changed to Closed Lost or Closed Won then it will ignore the Next Step Validation Rule.
AND( ISCHANGED( StageName ), NOT(ISCHANGED(NextStep)),
Probability<>0 || AND( ISCHANGED( StageName ),
NOT(ISCHANGED(NextStep)),
Probability<>100))
I added the OR option and it still does not work. Thoughts?
