Debt Reduction / Snowball Calc for Numbers?

I've been trying to import/re-work the vertex free version of the debt snowball calculator to use in Numbers for Mac. However, it isn't translating formulas, and the creation of the formulas to show how it can snowball isn't working either. I saw this thread from a couple of months ago

Debt Reduction Calculator for Numbers?

Someone put an iCloud link for a NUMBERS version at the end of the discussion. Unfortunately, the iCloud link said the version/compatibility wasn't updated by the owner. I would love a download file of this if it does, in fact, work as the vertex version did in Excel. Thanks so much, in advance, for any direction you can give 🙂
