It is modular so you create one set of actions
You could use ‘inline formatting’ to determine by using the :formatted as text operator
Calculation: Current date/time extract year - users graduation year is greater than or equal to 5 :formatted as text
Then in the format as text Yes: current date/time extract year - users graduation year is 5:formatted as text and keep yes and no values as yes and no
In the second format as text NO (ie: when the year is not 5 - this means it is greater than or equal to 5 but is not 5) you perform another calculation to compare against 10 and continue this formatted as text
There may be another way to do it using MODULO operator which may make the process easier to setup and manage in the long run, as I’m sure the MODULO operator can confirm if the year difference is a multiple of 5.
