Cannot deactivate account using workflow

Hi Community,

I am trying to deactivate an account using a workflow.

Simply choosing change status from the dropdown menu does  not work as i have to first set the status reason, but this is where i get stuck.

The status reason (statuscode) field is added and visible on the account form, but when I pull up the account form from the workflow proces when selecting 'update record', the field is not showing ...

Any help is much appreciated.

Thanks, Debbie
