Date to a variable

[#1]

Hi,

I have three list box, for year, month and day.

If the user selects the date, I want to pass that to a variable as vPickDate.  And then I want that vPickDate in chart expression.  Like select data when vPickDate is greater than Planned Date.

How do I pass the selections made in day, month, and year to one variable and use that in chart.

I appreciate any help

Thanks

But SET gives that as a string and doesn't populates the variable when some thing is selected in the list box

you need to use $(vPickDate) in your expression

I am still trying to create variable in edit script using the line

LET vPickDate = MakeDate(only(Year), only(Month), only(Day));

and that gives me script line error.

Thanks!
