Hey Brett Carpenter -
First off, yay for getting Bizible up and running! Great news!
As for your question, are you saying that you have a Salesforce campaign with touchpoints enabled for responded only, and the TPs aren't being attributed to the members with a responded status? Just want to clarify on that, as I think that's what you are asking but not sure.
If so, a few things you can check on is to look at each of the campaign members that have a responded status (I'd check them in SFDC and Marketo, as the Marketo activity log can be really helpful to see if something broke down someplace) and see if they have any touchpoints at all. This can help you understand if it's something that is broken in the campaign itself or if it is something that is broken on the SFDC side. This can also be helpful for Bizible Support if you open a ticket - they often need some more info from the Marketo side. Second, make sure that the responded status is what you wanted and expected it to be in the SFDC campaign (under advanced setup), if that checkbox isn't checked under the status you wanted then those folks definitely won't have TPs.
If it's something completely different than this and I was off understanding your question feel free to hit me back!
Hope this is at least somewhat helpful.
