Counting Expresson not working.
I add this expression to my Source text and I keep recieving an “invalid numeric result(divide by zero?) error.
If I change the “myNum = time” no error, it displays time + percent. Also if I just link to the slider, no error, my number is displayed.
It’s not that I can’t just put a percent sign behind the counter, I want to know why this isn’t working
Thanks,
myNum = effect("Slider Control")("Slider");
myNum + "%"

Sometimes the expression engine doesn’t automatically convert expression control objects to values and you have to explicitly tell it to do so, like this:
myNum = effect(“Slider Control”)(“Slider”).value;
myNum + “%”This is another way to fix it:
myNum = effect(“Slider Control”)(“Slider”);
“” + myNum + “%”Apparently forcing the string conversion (with the “”) also causes the value to be retrieved.

Thank you Dan, that was driving me nuts. Good thing to remember for the future.
