Are you sure you have the Photogate & Pendulum object selected?
not Photogate with Solid Object?
It is farther down the scroll list from the first photogate objects,
2 or 3 screens worth, on mine.
There is a Photogate and Pendulum object which measures the period by default.
It doesn't just double it, in case you are not exactly in the middle,
it counts A interval and then B interval and then adds them, works great.
We use separate lasers and sensors instead of photogates.
