XML in ASP

[admin]

I have to make changes to an ASP I did not create.The problem that I have is that I have an ASP that I navigate to from a linkon another page. This link passes in a variable through the URL. If thisvariable has a value then I want to skip a function call on the new ASP.The function call is made as the page loads but outside the <FORM> tag. Theactual <FORM> tag is inside an XSL file. The XSL file processes the XML file.I need to assign the value that is passed from the previous page to a hiddeninput box on the current page when the page first loads. When the page issubmitted I need to grab the value from the input box, determine if it hasa value, and then make the function call or skip the funciton call.How do I put VBScript or Javascript in the XSL file so that it will run afterthe input box on the form has been created? Also, how do I access the parameterbeing passed from the previous page? Can I use Request.QueryString?TIANate
