Error with IsNull function
We have a requirement to set Vesting Period based on Person's Probation Period. If a person doesn't have any Probation Period, then there should be no Vesting Period for that person. To achieve this, I have used below formula.
But while compiling the formula, I'm getting below error.
"line 20, either function IS_NULL doesn't exist or the combination of parameter types doesn't match the statement."
What is the mistake I'm doing here and how can I overcome this error?
Thanks in advance!
