Hi again,
you don't need a filter for this, see this example-button:
\define get-concatenated-value()
$(myrow)$!$(userInput)$
\end
<$button>
<$set name="myrow" value={{!!myrow}}>
<$set name="userInput" value={{!!input}}>
<$action-setfield $tiddler=<<currentTiddler>> $field="myrow" $value=<<get-
concatenated-value>>/>
</$set>
</$set>
OK
</$button>
Thanks for your help but in fact, in my case "fourth element" represents a
> variable that contains an input of the user (through the edit-text) and
> that can contains spaces inside.
