Right, I originally setup an array of my max and min values but the end result was obviously invalid due to that fact. I will just go ahead and calculate it how I have been (the brute force way). This would be a good tool to have in Mathcad. Developers take note!

Brute force does only make sense with just a few parts as of the increasing calculation time. And you never know if your grid wasn't too coarse.
I once wrote a very general brute force routine for that purpose for someone who asked. It deals without modification with any function in as many variables as necessary. Arguments for resistances, voltages, etc. are vectors as dense or coarse as you like. But for many parts and very dense grids it runs "endless" and gets useless.
You find the routine here http://communities.ptc.com/message/199660#199660
or here http://communities.ptc.com/message/228123#228123
but unfortunately its in Prime format. If you can't read it and are interested, the best I could do is to provide a pdf printout, as there is no way to convert Prime to real Mathcad.
In case of more parts a better approach might be to use a solve block with maximize or minimize and add the ranges for resistances, voltages etc. as constraints in the block.
