when visually hiding an asp.net control -- the javascript calculation stops working

attached is the javascript routine I used to calculate a value.

Some of those controls are visually turned on or off within web-page, depending on what the user selects...but the problem is that when one of these controls are visually hidden -- the calculation stops working.  I was hoping that the javascript would still calculate a hidden field.

label1.Visible = false   is how the control is hidden (server-side c#)Start Free Trial
