Change Reinvestment Amount

Hi, All.

I have a spreadsheet that I would like to revise, but I can't figure out how to edit the formula. Can anyone help?

The file was too large to upload, so I posted it online. Here is the link:

Under the 'Main' tab, I would like to change the 'Interval Re-Invest' at the top, to include 3 options, instead of the one:

Interval Re-Invest @ 1,010
Interval Re-Invest @ 5,010
Interval Re-Invest @ 10,010

For the 5,010 and 10,010 options, the invest amount would need to be changed to reflect that, so that each time the lending wallet has the funds to support it, it will show the invest amount accordingly. So, the Re-Invest @ 1,010 would not need to change, but the other two would need to be added and changed. I hope that makes sense.

Thanks!
