I have following two hidden variables-- addlist and rmvlist which get populated by clientside javascript and on page load i retrieve them as follows
    addlist = Request.Form("addlist")
    rmvlist = Request.Form("rmvlist")
after doing some operations i want to set them to bet set to empty or null.


how can i do that ????


Also i have a function which is called when
Request.Form("btnAddRmv") is true ( where btnAddRmv is a button ) i am doing this becuase i want the function to be called only when the button is clicked and after validations using javascript .
now the problem i am facing is that if i refresh the page after the first succssful run even thought the button is not pressed but it calls the function.
any suggestions how can i avoid that.

thanks

To avoid the function to be called put one hidden variable and set some flag when button is pressed and after the operation set some other flag.This way you can avoid.
