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?
