Hello,

I’m blocking on this all the weekend.

I’m trying to build dynamically a variable with “item” for browsing in a list.

`

- debug:  
msg: "{{ item.dev }} "  
loop: “{{ nginx }}”  
`

This is working well.

But I need to have the choice of the environment.

I tried this:

`

- debug:  
msg: "{{ lookup(‘vars’, ‘item.’ + environnement }} "  
loop: “{{ nginx }}”  
`

The output is:  
`

fatal: [localhost]: FAILED! =\> {“msg”: “The task includes an option with an undefined variable. The error was: ‘dict object’ has no attribute ‘item.dev’\n\nThe error appears to have been in ‘’: line 22, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - debug:\n ^ here\n”}  
`

I tried a lot of thing, but I didn’t find the right one.

Any advice?

Thank,  
Guillaume

Because of the quotes item is a sting not a variable.  
Correct syntax is

&nbsp;&nbsp;{{ lookup('vars', item['environnement'] }}

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: "{{ item[environnement] }} "
