Hi Everyone

My original set of formulas (bottom section) works as expected; however, as you can imagine, thousands of cells containing these formulas is putting a major strain on the workbook -- therefore, I attempted to convert the original into dynamic arrays and have spent hours trying to figure out why it will not work. Any guidance would be greatly appreciated - thank you.

What do {} around a formula in the formula bar mean?
{Formula} means the formula was entered using Ctrl+Shift+Enter signifying an old-style array formula.

Sorry, just realized that I didn't include a key formula in the "S-Curve" section

Hi Again -- I know this one is a mouthful but I still cannot figure out why this won't work. Any thoughts?

On that table you have a custom function DATEDIF(sStartDate,E6,"m") which is not defined anywhere.
Name sStartDate refers to a Sheet called Setup which you didn't mention.

I would be easier and not as time consuming if you could upload the file

I really appreciate you taking the time to assist! I don't believe we are permitted to upload a file anymore. Do you have an alternate preference?

You can upload the file to a cloud storage (like google drive, dropbox, etc) and share the link here. That is not prohibited as far as I know.

I included a link to a OneDrive folder because the dynamic array formulas may not render properly because of Google Sheets
