ditto extenders "distinct"

Hi,

We are using ditto and we love it !! But for a project we needed to use the "distinct extenders"...following the post, we put ".... &extenders=’distinct’ &distinct=’trucmuch’..." but it doesn’t work... it seems that it doesn’t care about our distinct...it just returns every single record in the database...
have you ever heard about this problem ?

Thanks in advance ?

Use backticks and not single-quotes: `

thanks, but i use backtips... it was juste for the exemple :

here my ditto call :

[[Ditto? &tpl=`liste1contratDisponible` &extenders=`distinct` &distinct=`annonceContrat` &parents=`689` &display=`all` &depth=`3` &hideFolders=`1` &showInMenuOnly=`1` ]]
