[Request] Autoit AH Help

[Rosulm]

So I have a very basic autoit script that I use manually to buy items on the auction house but it currently cannot change the max buyout price, does anyone know how to make it so an autoit script can automatically change a buyout to increase by 1 repeatedly? In 800x600, my current autoit script searches, clicks the item, hit buyout, then hits ok, and then clicks on the last number in the buyout so all i need to do is hit backspace then a new number and hit the autoit again. Any somewhat simple ways to do this?

tl;dr : Can anyone modify my autoit search to include changing a buyout price? Can post it if needbe.

I am getting an error saying 550000 += 1 --> Error: Unable to parse line. 550000 being my maxbuyout.
