All the D6 file download instructions don't work for D7. Now that everything is in Rules instead of Conditional Actions it seems there are more things to do?
I've tried setting up the action "Send an order email regarding files" after setting the completed event.
However, one thing not mentioned in ANY tutorial and/or thread are the required Data Selectors. It says I have to set the Data Selector for Order and Data Selector for File Expiration. None of the selectors are intuitive and I have no idea what to do here.
Can someone either tell me what to do for this in D7 or at least point me to the relevant thread, documentation, or tutorial for setting this up in D7. All I want to do is send a customer an email with their link once they pay for something.
Thanks
