Your blocks will attempt to force the loop index, i, to be zero. That’s a bad idea! What were you trying to do with the Row\_number variable? I assume you wanted to find a matching row value and then display the image from that row. Did you mean to set app variable Row\_number to i but accidentally swapped those?
