After a bit of trial and error it worked. I'll try to post a screen shot later of what I changed in case it is useful for others. Thank you for your help, much appreciated.

Hello, thank you for responding. Is your message "...wrangle to the fore output..." an autocorrect misspelling of what you mean. If not, I do not understand what you mean by "fore". The Solver Network is in the below image. The closest I can find to what I think you are writing about is the "For..Each" loop. Can you please elaborate for me? Thank you

I don't know about subnets, but if your intention is to create a HDA then you can set inputs/outputs by editing type info (I.e.where parameters are maintained).
