My answer only works for "NON-SORTED" concepts! The code below shows the name of the selected item on a CBC task shown on previous pages.
[% Begin Unverified Perl
CBCDESIGNLEVELTEXT("TL10_Random1",CBCDESIGNCONCEPTVALUE("TL10_Random1",VALUE("TL10_Random1")),2);
End Unverified %]
The 2 at the end changes which level's text will be shown. I've had conditional display, so using 1 as the last parameter brought me the img source.
The "CBCDESIGNCONCEPTVALUE("TL10_Random1",VALUE("TL10_Random1"))" part, gets which concept was shown as an integer, 1,2,3,etc. Using this as a parameter to CBCDESIGNCONCEPTVALUE, one can obtain different levels as well, just concatenate them within your perl code.
