Error message when sending iTunes gift by email

I get an error message when I try to send an iTunes/apple gift that says "Invalid Gift You must enter your sender's email address." I go to the "send gift" page, enter a recipient email, the amount and date to send. My apple ID is an email address, but it does not seem to recognize it in the "From" field. I tried my secondary email tied on my apple account and tried logging out and back in to apple ID, but no luck. I have successfully sent funds to the same recipient in the past using this method. So frustrating. Any ideas?
