If I apply for a job, and miss their call, do i call back?

I went into an athletics/sporting goods store to apply for a part time job. I asked a store supervisor about applying there. He said to do so online and then call and ask for him. So i did this, and he said to come in for an interview. I did and it went well, however he said my online application did not work so he asked me to fill it out again and he would call me back. I did so, and he called today. However, I was working my other job at the time and missed his call. He left a message saying he'd talk to his manager about job availability and give me a call Monday. Should i call him back to let him know i got his message? Or do i just wait for him to call Monday?
