Hi,

I’m trying to send a POST HTTP request, using data provided by feeders (one from a JDBC and one from a CSV).  
The feeders are working well (I tried to print the session, and I found my values).

But when I try to use these var inside my post like

**.exec(**  
**http(“my post”)**  
**.post(“my\_url”)**  
**.param(“pt:name”, “${USERNAME}”)**  
**).pause(1)**

This does not work. If I replace **${USERNAME}** with a **static value** , it is working perfectly.

I thought that param(…) is a function that handle the Gatling session… What am I missing .?

Thanks !

Mat
