Did you "Run Synthesized?"
Unless you choose this special "get it started mode" eValid won't
do the parametric substitution step before each playback.
To have one script run repetitively, after adjusting values of parameters
in your script, you can use the powerful eValid Data Synthesis capability
(this capability also works in LoadTest runs also): http://www.e-Valid.com/Products/Documen ... .data.html
I hope this answers your question.
