I just bought a Minolta Maxxum HTsi camera. I took an entire roll of film in order to get familiar with the unit. When I took them to be developed, there was nothing on the film at all. Can anyone tell me why? The photo clerk said that it had not even been exposed. PLEASE HELP

It sounds as though the film may not have been advancing. I'd suggest taking another roll of film as a test. If the same thing happens you will need to get in touch with Minolta technical support or return the camera to the store you purchased it from. When testing your second roll, be sure that the film sprockets completely line up with the gear wheels so that the film stays in place and advances correctly.
