Dimension members in text box

I have a bex query with 2 dimension members(comment1, comment2) as per snippet below.  There is comments per KPI code(STRAT039 and STRAT041)

I would like to add the  dimension text values(comment1 and comment2) per KPI to a textbox

I tried to add al the comments firstly to a dropdown as per below code but only the first comment is showing.  Perhaps the syntax for the concatenation isn't correct.   I've got 72 KPI's so this way would be a lot of coding so I'm hoping there is a better way.  The data for the measure is displayed using the bound function.(see current performance) above so is there no way to retrieve the dimension text from the bound value perhaps
