Need help with Timer expression

Hi, I want to activate a timer when a date is between two dates, I have this but it doesn’t work.

timeBetween({Root}, {Root}, {Root})

I apreciate any help thanks.

What values does {Root}, {Root} and {Root} have?

What is the expression bound to?


The three are pop up calendars, and the expression is in the running property of the timer. i have proved this, but it doesn’t work.

if(timeBetween({Root}, {Root}, {Root}),{Root Container.timer.running}=1,0)

I resolved it, I don’t realized that the first argument is the given date.
