Experts,please modify this AFL

[chilgu]

I found this AFL from http://www.wisestocktrader.com/indicators/2149-amazing-buy-sell-signal.

This shows buy-sell signal alongwith trailing stop loss and profit target, but SLTP and profit target fields remain empty. I do not know programming.
Any expert, please modify/correct it so as to the AFL can generate complete result.
