[TYPO3-english] Custom Layout Dropdown in Powermail

[Scotty C]

Hey all,
I'm using T3 6.2LTS with Powermail 2.25
I need to have custom layouts beyond "layout1 ... layout2 ... etc" for some fields in my form. Essentially, I need to apply classes to the field(s) so I can style them. Documentation says I need to put this in Page TSConfig:
TCEFORM {        tx_powermail_domain_model_forms {      css {        removeItems = layout1, layout2        addItems {           blue = Blue Form           green = Green Form        }      }     }     tx_powermail_domain_model_pages < tx_powermail_domain_model_forms     tx_powermail_domain_model_fields < tx_powermail_domain_model_forms}
However, when I do that, nothing happens. I still see "layout1 ... layout2 ... etc". Clearing cache does nothing.
What am I missing? (Thanks!)-Scott.
