Use a external parameter in a foreach loop container

Hi

I use a parameter P1 in a package

This package contains also a foreach loop container including a parameter P2 (P1 is on outside of the foreach loop container)

In this foreach loop container, I need to insert into a table T1 the parameter P1 and P2 from an execute sql task :

INSERT INTO T1 (F1, F2) VALUES (?,?)

My question : how to access to the P1 parameter in the container ?

Thx for your help
