edited, sorry answered the wrong thread...
for your holiday cost tv in the template, the YAMS call should be
[[YAMS? &get=`tv` &from=`HolidayCost`]]
now when it comes to have it in chunks, the easiest way i’ve found out to do this is to do it the YAMS way in... YAMS call
i generally use two chunks myChunk_fr, myChunk_en for example in which it easy to output [+myTv_fr+] and [+myTv_en+] and use &tpl=`myChunk_(yams_id)` in YAMS call
so far, no issue with this way of working
now, when lazy
i may use only one chunk and, in this chunk, call a snippet to output the correct language tv content...
this is quite easy with a snippet as with
$yams = YAMS::GetInstance();
$langId = $yams->GetCurrentLangId();
on top of it, you retreive the language currently used but this lazyness is paid by one more instance of YAMS even if fankly it does’nt seem to impact perfomance
hope it helps despite my "heavy English"
