Hey I am using ASP .NET 2008 (3.5) with C# code behind also using jquery. I want to be able to setup a way so that if a customer clicked on our google adwords it would display a different contact number on the website page. The phone number on the webpage is in a span with the class labeled "phone". So basically if they have reached the site by clicking on the adwords I want to display a different phone number and if they have not reached the side by clicking on the adwords to leave the phone number as is.
