3 MA crossover e-mail alert

I’m currently using FxPro’s MT4 demo account. I have added this 3 MA crossover alert (which I downloaded from somewhere else). After I set to new MA periods, it still did not capture the new settings (it still shows the old MA periods).
I also want to have an e-mail alert just like the 2 MA crossover alert below (it also not capturing my settings).
Can someone advice how to make my new settings captured and have the e-mail alert as well ?
All I want is an e-mail alert of the 3 SMA crossover.
