on clicking edit option in article management, system gives error - This feature is not currently enabled either for this record type or the given user type or org
Any pointers as to what I might be missing?

I get this error: Challenge Not yet complete... here's what's wrong: 
The Suggestion custom object does not contain the correct set of custom fields. Tip: check for typos in the field names.

I've followed all steps, went back and rechecked, and then redid the entire challenge. I can't get it to pass. What am I doing wrong? I have included all custom fields and spelled them correctly.

Hi folks, 

I try to complete the "Build a Battle Station App" -> Modify the User Experience. Trail to complete. I checked everything and did it 3 times but every time I get the error:

Challenge Not yet complete... here's what's wrong: 
The 'Resources' related list was not found on the Page Layout 
Note: you may run into errors if you've skipped previous steps.

The Resources Column is in the Page Layout and I add the needed objects. 

Anybody an Idea?
