This is a follow-up question of my previous one:
Cross-referencing numeric values and text from later section to executive summary of a latex document

I have finished making my report and now my boss asks to insert an index into the document.I have made a sample as below (the tex file is created using Rmarkdown and pandoc, so it may have some code not needed but incorporated)

I create a list of terms and cross-referenced them in other part of the document, what I want to the index each and every one of the terms so that they can be listed in the index part (i.e. cross-referencing label03), but it is not working.

What have I done wrong? Thanks!
