I'm not sure excatly what you're trying to do.
But if you want to display the result of an evaluation of a user input one way to do it is (in the example below the data to evaluate is sent from a form element):
Form action asp file :
dim var_name
var_name = request.form("form_field_name") '+ some evaluation'
response.write var_name
Or you could:
Form action asp file:
dim var_name
var_name = request.form("form_field_name") '+ some evaluation'
response.redirect "page_to_display_the_data.asp?responsenumber=" & var_name
Asp file to display the result:
response.write request.querystring("responsenumber")
