[TYPO3-english] TS: is there a way to count() for elements GP-variable?

[Bert Hiddink [BENDOO e-work solutions]]

Hello Loek,

Thanks for your reply!

I tried the userfunc first, this works...

However, besides some constants, I need to pass the value of the current 
uid to the userFunc (please see below) which is rendered from the  30. 
object...

However, within the userFunc it passes the uid of the Page instead of 
the uid of the current category...

Any idea how to resolve this?

Thanks again!

Regards,
Bert
