Sketch wont compile or upload

The progress bar starts then hangs on compile or upload ive tryed this on 2 laptops now both have the same result, ive waited 1 hour and its not getting any further along.

the skech is

im uploading this to an uno.

There may be problems with the sketch (ie the code is wrong or brackets are in the wrong place) but this shouldnt stop it compileing.

Any help greatly appreciated

Yes it will. Correct the brackets.

Thank you

I knew id missed summat
