I got an error also, it wanted to download some dll's or something.
Looks like a nice program you have setup there. I've used YNAB ( You Need A Budget) for my numbers, but I find it to be too in depth. Your's looks like it would be just the ticket.
ok fixed the issue i had.
that is what i get for posting at 4am after i finished it.
I can not edit this post now but i will upload it here for now.
well its to large to upload here so use this link.
Download the program here ----> https://www.dropbox.com/s/q7qn0c9xfqwwfqh/leaseFinal.zip?dl=0
If it ask you to sign up or login just X it out and download.
