Help! Cannot Extrude Sketch

andrew_pfeil100

For some reason, I cannot extrude my sketch. It's not a very complex shape, but I think it may have something to do with the fillet feature. I've included the document below:

Any help would be much appreciated, I'm new to this software, so I'm hoping it's just me being unfamiliar. 

I think this question might be academic in nature, I'm almost certain I could remove the fillet and extrude first, then fillet the solid. I'm not interested in that workaround, because I anticipate more complex sketches that need extrusion in later designs.

Your profile isn't completely closed. If you open the sketch, look for blue dots. Those are points that are unconstrained (not fully dimensioned). One end of the large circular arc isn't connected to the straight edge, creating a small gap when you zoom in. Also, there's a blue dot on one of your corners. I'm not sure what the issue is with that one, but that corner may need to be cleaned up as well.

Thanks Tim! I didn't see those the first time I looked, but that seems to have done the trick
