Require a date field entry to be after a date ente...

[Rose_Haft1]

Hi - I am trying to do a daily balance and bills owed table and am wanting to match expected income so that the dates match. Ideally it would also have a daily exchange rate. 

I am just not sure how to match and roll-up based on varrying criteria without needing a new column for each date. 

How do I do this? Do I need a third table?

Hmm, yeah I think you'd need a new table where each record represented a single day:

And you could use automations to link the records appropriately.  Not entirely sure I understood your question though, sorry if I got something wrong!
