Receiving multiple purchase orders with one receipt

SOLVED

Hi,

I'm trying to figure out why the button to enter multiple purchase orders against one receipt in the receipt of goods is now showing, I've followed the help files and made sure the four fields, dealing with ship via, tax schedule, etc... were all the same. But the button does not show up. I see it in the customizer design mode, but don't know why or how to get it to show in the form itself when entering a new receipt. I tried to look for a configuration or checkbox that turns this on in the setup but can't seem to find anything. Am I missing something?

thanks
