Very good, thanks Rob. I’ll dig into it.

Hey Rob, I am getting this now, "

The name can only contain underscores and alphanumeric characters. It must begin with a letter and be unique, and must not include spaces, end with an underscore, or contain two consecutive underscores."

Here is the iframe I used from the thread you mentioned.

Here is a screen shot of the layout and referenced VF Page. Any quick ideas? Thanks again!

VF Page Referenced below.

Aha. Box.com. We’ve seen this before.

First. You don’t wrap your VF Page name in <> That is why you are getting the error message.

But Second. Because the VF page is really just generating an iFrame and passing parameters to it, you can bypass the VF page entirely and just put the iFrame with parameters into the template component in your Skuid page.

Here is another forum post where this is described: https://community.skuid.com/t/adding-a-box-custom-component-or-template-to-my-page

Cheers.
