Hi, I created a form without code in IP 2013, just rules and data connections to sharepoint lists. The remove code button is inactive, so I assume I did not add any event handler accidently. I con't publish the form as SP content type directly because IP tells me that it requires Admin approval. What can I do? Thanks

What version of SharePoint? Is the trust level set to automatically determine? That is, it didn't accidentally get set to full trust?

It was full trust, I reset it to domain and it works. Thank you!
