The attached revision of your efs should now work.
However it will generate the alerts on every tick for the whole duration of the bar that triggers them. At this time due to some limitations in the Formula Wizard it is not possible to correct this using only the Formula Wizard so the efs will need to be modified using the Editor. Once that is done though you will no longer be able to use the Formula Wizard to further edit the efs.
The alternative is to write the formula so that it only triggers the alerts at the completion of the bar. This can be done using only the Formula Wizard.

bollinger band price alert second try

The attached file is the one previously given and modified with the wizard. The desired output should only happen once per penetration of bolinger bands by price. Can any one confirm?

Looks like it will alert you, beep and send an email only once per event.

In addition to what David has said it will also trigger one event only per side.
However there is an error that I failed to notice when posting the revision. In Set 2 the conditions are
low(-1) > vBollinger20.getValue(BollingerStudy.UPPER, -1)
low() < vBollinger20.getValue(BollingerStudy.UPPER)
but should be
low(-1) > vBollinger20.getValue(BollingerStudy.LOWER, -1)
low() < vBollinger20.getValue(BollingerStudy.LOWER)

It is working correctly and triggers one alert only per event and one event per side (ie Upper then Lower then Upper etc). In the image below the arrows indicate where the alerts were triggered.
