Can't copy and paste short code

I want to collect email addresses using Hustle Pro and I also need to know whether the person is a student or a parent so I created a custom thing. I used Contact 7 and I'm rather pleased with how it came out. The problem is I can't figure out how to get it onto my site. I've tried creating a widget (like 6 times) but could never get it to work. Then I thought maybe I can just paste the code (using Upfront) but when I copy the code, it doesn't carry over so i can paste it.
