Hi,
We have a customer who have an alternative week description, their year runs from March to March, so their week 1 is ANAPLAN's week 9 for example.
I have created a list 'Weeks' and this has the 'Reak week' and also the alternative week (currently in text)

Then in my module i want the Alt Week to show... but i do not know how to LOOKUP this using the period , time, week ????

Any help or guidance would be appreciated, even if it is a simpe,as it seems...
Thank you
