Can someone review my Script... Loop doesn't seem to be work

I wrote this to assist our accounting department with invoice entry from a controlled excel file. I have everything working pretty well until it gets to the loop for multiple receivers. I have tried using "Loop Lines - 1 {" and "Loop %Lines% - 1" but neither works. If you notice the large amount of sleep time, we have a very old system and it needs the time delay.

Can someone take a look?

Thank You!

Would you know why the ^c inside the loop isn't working?

You could try Send {ctrl down}c{ctrl up}
You can simplify / shorten your code quite a bit like so

SetKeyDelay, 150
; ... you can now remove all / most sleep 150
Send {Down 5}{Enter}{F8}

Awesome! That works beautifully. This may be the last thing.

Because the amount of invoice lines change through the excel document, I want it to set up a formula in excel to get the number of line and copy that number (My macro already does that), but now I need to find a way to input that data into the macro itself. I tried using an input box, and using Ctrl+P and Enter, but it does not do it. I also tried having the mouse click in the active cell, but that didn't work either. How can I accomplish this?
