[TYPO3-templavoila] accessing fields outside repetitive Containers width Typoscript

[Lukas Taferner]

Dear list,

I have a problem with repetitive FCE's: I try to set up a Gallery 
element with multiple Images. The width and the height should be set 
OUTSIDE the repetitive Section (i.e. only once for the whole FCE). 
Unfortunately I cannot access 10.file.width.field = field_imagewidth 
from INSIDE the repetitive Element:

field_width
field_height
    <repeat>
       image [file.width.field = field_width]
    </repeat>

Any help is appreciated!

best regards,

Lukas Taferner
