What is the best way to handle dynamic parameters in e-test? I have a situation where a system generated number is appended to a parameter name and playing back the script just adds the newly created parameter (name + generated number) to the parameter list and using the originally recorded value.

I tried created a Before scriptlet that looks something like:
Dim paramNameAmt, paramValueAmt, resultb
'example of paramNameAmt is quote_amount_77777_99999
resultb=rswObject.play.nav.setParameterValues(para mNameAmt, paramValueAmt)

The above scriptlet did not seem to set the value.
