I'm having a problem trying to call a string, which is given a value and manipluated in the c# code behind page, my question is how do i call this string in the .aspx page, so that i can use the string as a parameter as part of a url?

I'm building a string for calling a webpage from query strings sent to the page, which i then want to take the final string and use this as part of the url for a javascript call to open a new window.

But i don't know how to get the value of the string to show in the aspx page, i know it may sound like a noddy question but any help would be appreaciated.
