pdf template problem in table

[Lokki7]

Hi,
I have this template.

<<Start: [Locali]>><<[Nome]>>
<<Start: [Impianti]>><<Start: [Parametri]>><<Start: [Misure]>>
<<[Tipo]>> - <<[Materiale isolazione]>> - <<[Materiale rifinitura]>> - <<[Diametro]>> - <<[Prodotto]>> - <<[Misura]>><<End>><<End>><<End>><<End>>

And works well.
If I try to format it inside a table, I can't get it to work.

From the error I get it seems that Start expression '[Parameters]' does not generate a List of Ref values.

How can this be resolved?
