for-loop - Adding a condition to Amibroker code

Question

This is my Amibroker code for a 2 bar swing chart, I need to add a condition that if price falls below the previous swing low in one bar, then to treat it as a two bar move. The problem I have is, holding the last swing low price variable to check against todays low. I have commented the problem lines in caps. What I have I thought would work but the condition is not showing up on the swing chart. Can someone tell me what I am doing wrong.Thanks.
