Thats the place, hopfully they will update it with an Arma 2 one soon. So far I only have got one or two to work, big ones though. A lot them from Arma 1 just create an explosion with no sound, I haven't checked if they even do damage, it may just be smoke.

If you open up the trigger again you will notice the 'Activation' drop down box has changed and now contains 'Vehicle', 'Group Leader', Whole Group' and 'Any Group Member'. These are all pretty self-explanatory except that 'Vehicle' means the specific unit you grouped it to, regardless of whether they are in a vehicle or not.
A small trick I use to ensure that the trigger is set up properly and activated when it should be, is I use this line
This will make it so that when the trigger is activated you character says "Trigger Activated" so you know the trigger has definatly been activated.
player sidechat "Trigger Activated"
So is your character says "Trigger Activated" but nothing happens then you know it's the code you used that is the issue and not the trigger parameters.
bomb = "Bo_GBU12_LGB" createVehicle getmarkerPos "explosion"; player sidechat "Trigger Activated"

(most should still apply to Arma 2)
combined with this:
Arma 2 Command Reference
should help a lot with other aspects of editing.
For a grenade sized explosion, this should work:
grenade = "grenade" createVehicle getmarkerPos "Markername";
