It now works
one of the problems seemed to be was on the parent page I had the rich text editor on and as soon as I turned that off and changed the & to & it all seemed to start working obviously with the other changes from Bob which I am so thankful for.
So now I have a call of
[[getResources? &parents=`49` &tpl=`showroom` &tvPrefix=`` &includeTVs=`1` &processTVs=`1`]]
and my tpl chunk has [[+showroom]]
Next job it the pagination so maybe more posts to come on that but hopefully not many thanks again.
Cheers
Ian
