Sumprod formula to exclude string values

Hi there. Hoping to get some help as I can't figure out how to exclude string values. Tried searching on site for answer to my question, but could not find it.

Question is...in the below formula the red are pointing back to name ranges in a different tab on my spreadsheet. On that spreadsheet I also have a name range called DTCCSUBSUPPREF

I would like to add within my formula, a string which will point to that name range and exclude values if they fit my criteria. Basically I need to see values only where comp or tri dont show up. comp or tri could be the only value in the cell, or could be in the beginning of a string, at end, or in between. Below examples. I have tried (--(DTCCSUBSUPPREF<>"*comp*")*(--(DTCCSUBSUPPREF<>"*tri*") , and I would have thought the * characters would have served as a catch all.

Below is the entire folumla just in case. Any help would be greatly appreciated!!!!
