I think I’m trying to write a loop. I am trying to switch the value of ims_dir (and eventually ms_dir too) depending on fulfillments of two if statements. I’ve tried declaring ims_dir = na, and then having the first if statement also accept ims_dir == na, but that messes with the if statements function. Really I’m just looking for a way to switch between these two if statements indefinitely depending on when they meet the criteria, but having to declare the variable that acts as the switch so I can have the if statements re-assign it’s value is messing with the if statements. I added <<<< on the right so you can easily find it, hope it helps.

Pretty sure this is an easy fix, but not sure how to do it. Thanks so much for your help!!!!
