Oven Debacle

I think that I have discovered what is wrong with my oven without the help of the repair man. As I was trying to get dinner cooked last night before heading out with Sydney and Michael I came to find the oven wasn't as hot as 450 degrees should be. I was using the timer on the oven, so I turned the timer off and the oven started to heat up. If it could only be as easy as this my prayers will be answered. If not then I'm back to square one:). Lesson learned, is use the timer on the microwave and dinner will be on the table on time.
At least I'm in the kitchen trying to get real food out! Thank you my friends for helping me with this.
