Passing order number to new link

Ok, I have an odd question. The cart I'm setting up is for a print service. We have a seperate FTP program and script for uploading files, but my boss wants to be able to put the order number into the link to the FTP script so it will fill out the field automaticly. Is there any way to do this?

You can get the order number from Zen Cart but is this not a question for the seperate FTP & script source. We do not have any idea how to insert this into anothers script

I'm not asking about the FTP program. What I need to know is if there is a way to grab the variable for the the order number from the checkout page. So, basicly, on the checkout page there will be a link to the FTP script page that passes that variable to it.

Order numbers are not created until the order has been confirmed.

I know, then it displays it on the confirmation screen. Is there a way to grab that number so it can be put into a link? I'm not sure I'm explaning myself very well. ><
