you should use the name of the param you are selecting, in your case, 2 x play *2. But the space character and possibly the number "2" would mess the expression and result in the following error message : "1. Parameter name does not conform to expression syntax variable naming rules. If you want to use Expressions in this parameter you'll have to change the name."

Simply name it "play" and fill the expression with "play*2". If you want to keep complete name for params, use "_" as space character or CamelCase and no numbers in the name.

At present most expression indeed use the Parameter name. This was a bad decision I made a long time ago, it would have been better to use x for everything. It's more predicable and less work to copy/paste expressions.
