Hi Bob,
Very easy, I do it all the time:
Use a "Regular Expression Extractor" Post Processor in the page that sends the
value you want. This will set a variable that you can use in your subsequent
POST.
The help and examples on "Regular Expression Extractor" are very good but
something like this should do ya:
Reference Name: enrollment_id
Regular Expression: registration[enrollment_id]" type="hidden"
value="([^"]+?)">
Template: $1$
Match No.: 1
Default Value: enroll_id_NOT_FOUND
Then in your POST wherever you want to pass the value you put ${enrollment_id}
When you test, if the value is replaced by the Default (NOT FOUND) value,
you'll have to adjust the regex appropriately.
Godd luck,
Bruno

Apparently, my mail program encoded the addresses, below and the mailing list
filter displayed the link inline. I have cleared the issue, below.

I am 75% sure that this will do what I want, with each thread using an
incrementing number for its run (the first will sign-up a user named
“[email protected]” and the 10th will sign-up a user named
“[email protected]” )
