[TYPO3-english] Typoscript usergroup condition with values from page record

[Edmund Huggett]

Hi,

Is it possible to use a value from the page record with the typoscript 
usergroup condition? Something similar too:-

"    [usergroup = TSFE:page|custom_field_name]    "

Is what I am trying to achieve (this obviously does not work), where 
"custom_field_name" from the page will store the group id(s) that I want 
the condition to match. I am currently using Typo3 4.5 .

Thanks for any suggestions

Edmund
