Hi,
I have the following code where there is some client side VBScript that
does something and needs to pass a variable back to the ASP.NET page.
When the page is updated through a postback, the information is lost.
What am I doing wrong?
After obtaining the variable, I assign it back to a Label text field on
the form, it shows up on the web page no problem.
During postback, the variable for the Label text field is blank.
Thanks for your help!
