Sorry about that. You provide the perfect solution for what I was asking for and I was hoping to be able to recreate it in my form. I was hoping for a solution that considered the use of a .xml file but wasn't clear on that. I should have provided a .xml the first time around but didn't think it was going to be that difficult for me to incorporate on my own, not realizing there was going to be such unique rules involved. I've incorporated everything you've provided into the attached test form, now I am trying to line up field 3 with the embedded .xml file rather than setting the default value so field 3 on row j. 1., j.2., j.3., j.4. and j.5. should have G-1, G-2, G-3/4, G-6 and G-8. I have about 20 more values to add to the .xml file once I get it working. You've helped me immensely and my form has come such a long way. Thank you very much.
