Hi Jeff,  
Thank you for investigating. I confirm that it doesn’t submit with the specified options (as checked in `/var/log/ondemand-nginx/$USER/error.log`).  
I’ve also tried to replace `bc_num_slots` with a custom variable as you proposed - however I get the following error message.

Do I have to replace `bc_num_slots` in some other files too?  
So far I have just replaced them in `form.yml` and `submit.yml.erb`.

`form.yml`:

> ```
> ---
> attributes:
> desktop: "mate"
> bc_vnc_idle: 0
> bc_vnc_resolution:
> required: true
> node_type: null
> ood_var_mem:
> required: true
> label: "Memory"
> value: 1
> ood_var_slots:
> required: true
> label: "Slots"
> value: 1
> 
> form:
> - bc_vnc_idle
> - desktop
> - bc_account
> - bc_num_hours
> - ood_var_mem
> - ood_var_slots
> - node_type
> - bc_queue
> - bc_vnc_resolution
> - bc_email_on_started
> 
> ```

`submit.yml.erb`:

> ```
> ---
> batch_connect:
> template: vnc
> script:
> native:
> - "-M"
> - "<% ood_var_mem.blank? ? 1 : ood_var_mem.to_i %>"
> - "-n"
> - "<% ood_var_slots.blank? ? 1 : ood_var_slots.to_i %>"
>
