Hi Jessica,
I would think of something like this:
Create a table with 26 records (the letters of the Alphabet) and add fields next to it that contain the numbers of the assigned months.
![NameMonth NameMonth](/t5/image/serverpage/image-id/10685iBFB663CFD3F4448D/image-size/large?v=v2&px=999)
In the main table (another table) add the names of the clients and each one of them link them to the first table. For example, Client John Adams is linked to the letter A, Nicky Lauder is linked to the letter L.
![NameMonthClient NameMonthClient](/t5/image/serverpage/image-id/10687i7A038A1A0B1C1D2D/image-size/large?v=v2&px=999)
In the main table you use the field type LOOKUP to find the Due months that are connected with the client and when this is done you are ready to see of one of these months equals the month of today’s date. If that is the case you can flag a field (Alert).
That would be something like this:
IF(OR(MONTH(TODAY())={DUE 1},MONTH(TODAY())={DUE 2}),‘ :triangular_flag_on_post: ’,BLANK())
It looks like this:
![NameMonthDue NameMonthDue](/t5/image/serverpage/image-id/10686i7ADCEE557C48C6F9/image-size/large?v=v2&px=999)
I hope this will work for you :slightly_smiling_face:
