CAMERA......

So this past monday I was able to borrow a BRONICA SQ-A (medium format camera) I was super excited to put some film in it and start shooting...however I have not been able to figure out how to use it! im so frustated. I've read the manual about 5 times and every time I thing I have it figured out, it turns out I dont. All I know is that so far i've ruined 2 of my 12 exposures, which makes me reallly sad...so I ask, why is it that whenever I press the shutter release button nothing happens?!
