InfoPath Dev

I've published this test form that I threw together really quick as a Site Content type. So I have a library that has this form as it's default form, but when a user submits it I want it to be stored in a different form library in a different sub site. The URL that I used for the submit is the url of the library minus the Forms/AllItems.aspx from the different sub site. When the user does submit it I get this error(see picture). Do I have to do something special with the library that I want the form to be stored in, did I forget something, or what do I need to do? I'm new to SharePoint and InfoPath.

 Is this a browser form? Is the only submit the library submit? Does the user have write permissions to the library? Is this Office 365 or an on-prem SharePoint install? If it is on prem, you should be able to give your SharePoint admin the correlation ID and she can look up the error details in the ULS logs.

Hello, Thank you so much for the quick reply! It is a web browser form, there is only one submit and it is to a SharePoint 2013 form library that is in a subsite to the root one. It is 100% SharePoint and no Office 365. I've looked in the ULS Logs but I am not sure what I am looking at.

You'll want to try the submit, copy the correlation error, then search the log files for that error. Any messages that give any clues?
