When posting state exactly what you are trying to do and post your efforts(prototype code) to date; stating which part is not working.
Are you trying to blink the led once; move the servo 90 degrees then blink the led again? Blink the led every 10 degrees while the servo moves from 10 to 40 degrees? State exactly what you are trying to achieve.
A good start would be to take the servo sketch and add a couple of lines to simply turn on the led then do the servo stuff. This way you can verify that both the led and servo can work together in the one sketch. (i.e. sort out which pins connect to what).
Get back to us with your results and a description of what you want to achieve.
