I'm looking at your email. I don't see a block where you want this video?
So I made a copy and I just inserted a Signature block under the last row of "Easy Shrimp Eyes" and "Easy Shrimp Legs".
I then clicked to insert a "Video Link" under the "insert options" on the left. I used this URL: http://youtu.be/5uRVd-UMXy0 and it worked.
Go ahead and take a look and let me know if you can do that as well in your own copy.
I just saw your last reply!
So glad you were able to get it working! You can delete my email from your account!
