Im trying to modify placement groups in a hook as indicated in 6.13.3.20 Plugins (Hooks) Guide (2021.1.3) but I get an error.

Here some background:

I do this using qsub as:

As the resource **two** is already a declared resource, submiting the job produce no error. I can also see the details of this submission as I have the current hook with with debug=True:

# cat /var/spool/pbs/server\_priv/hooks/tmp/hook\_queuejob\_correct\_queue\_1657526372.in

The main question is, modifying that resource in a hook should be something as (according to that section 6.13.3.20 from Plugins (Hooks) Guide (2021.1.3)):

but I get

If in the other way, I simply use the same wording as in guide:

 ![image](https://canada1.discourse-cdn.com/flex030/uploads/pbspro/original/1X/974bc9d0c9b32143a4767d188565197441fcd838.png)  
I get

Am I missing something? We simply would like to give specific **resource** values for pl=pbs.place(“group= **resource** ”) such as “two” or other resources we already have.

As always your feedback is so appreciated it.

Can you please try the below syntax:

```auto
#job.Resource_List["place"] = pbs.place("[arrangement]:[sharing]:[group]")

example:
jobB = pbs.event().job
jobB.Resource_List["place"] = pbs.place("pack:exclhost")

Thank you Adarsh,

This guided me to the solution. The reason of my confussion was due to I was using debug files that were missing the particular resource I was using. This was solve by simply running the hook and submit jobs.

Much appreciate your quick reply on this.
