Hi,
ParamDisplayValue is your friend :) If you do an Internet search using this keyword, you'll find lots of info on this frequently-raised topic, both on Cognoise and elsewhere.
Generally, you will want to display first a literal (a Text Item), such as 'Requested Date: ', followed by an expression such as
QuoteParamDisplayValue('pReqDate')
Give this a try. You will then probably encounter some formatting issues. It's usually best to put the above values in two columns in a table in the header of your report. Then you can play with left / right justification as well as the formatting of the date component.
Post back if you have further questions.
