I have afield with inventory numbers. There numbers start with a bin letter designator and then a number. ex, A2, G22, AA15, AB21
I was using the LEFT function to grab the First character to identify the bin letter, but now that I have grown and now have bins AA, AG, etc. How to I have have Airtable grab just the letters out of the field or grab two letters is the inventory has one?
Thanks,
