CarolPa, read the comments from the OP's site post. Some have success with gas ovens. It seems the way gas ovens vent, there may be an issue with the oven cooling down too fast. In cases like this, gas oven owners keep the oven temp set at the lowest temp setting after the high heat part.
One such comment from the original posters (OP's) site comment section:
"It will work in a gas oven…..but instead of turning the oven off…..turn it down to 150 degrees and leave it alone for 2 1/2. Worked great for us!"
