Hello, As I understand, you need the attribute nodes in side the loop, for monitoring purposes.
Your VI basically has data flow issue. The multicolumn list box does not allow you to set the symbol unless item name is set. In your VI, setting of Itemsym happens to run before setting the itemname. One solution is to create a case structure around the item name and connect the output of inner loop to that case structure. I hope this makes sense.
