Hi
The remember trigger is set to add new selections to the list of remembered selections (rather than start a new list each time the trigger fires)
It would be better to view the remembered variables in Engineer Mode. Just put sl_price_market_id_back_price in one cell in the Engineer mode settings. Then it will display the variable for each remembered selection.
If you want to view the remembered variables in Variable Viewer, you would need to add an index. See attached screenshot.
