Combine a multi-body part

Hi,

I'm having a hard time trying to merge one sheet metal base to another ( at an angle). I have two sketches. The one sketch I made a base flange. Next, I made a plane at an angle, then I created another base flange out of that. I get an error message when tick "merge result". I attached a file to this post. Can someone please take a look at this.

Thanks

Joe
