How to restrict EFS script variable data to only one page or window?

[diesel]

I have a script that I would like to run completely separately in a window in two different pages. At this point, when I load the script in a window in two pages, the variables get chart data from either or both windows charts. I would like each script to get only data from the chart window from which it is being executed. And, the charts data is for different stock tickers.
