Drawing wont extrude, even though it is a closed loop.

I cant get this drawing to extrude, but can't find a reason why. Any help please :)

    Hello Nicolaj. It's not a closed loop until it turns grey. What about these guys? - Scotty

    There are two ways to find out where the sketch needs fixing.

    First, the profile inspector:

    1. Open the sketch for editing.
    2. Click the "Sketch diagnostics tools" button

    3. Click the "profile inspector" button

    From there it will highlight the loose ends of the sketch:

    As @robert_scott_jr_ said: It will turn grey when the sketch is closed. Then it can be extruded.

    I find that a little clicky so I prefer to use my custom feature "Find open profiles":

    This shows the two gaps that the profile inspector finds but it also reveals a few other oddball bits of the sketch that the profile inspector doesn't report (which are dangling ends that do not prevent the sketch from closing). Maybe useful, maybe not.
