Setting user defined variable in beanshell not working

[Peter Moser]

Hi,

I want to set user defined variables in a beanshell.
I use this code: vars.put("user", "one"),

When I later want to use the variable in a sampler with ${user}, it is not
replaced.
With a debug sampler I can see the variable is set.


What am I doing wrong? Here is the xml of the project:

Error that I got:
FATAL: role "${user}" does not exist
