Team Upgrades

Team Upgrades

I am trying to set up a trigger that will upgrade for a whole team. I want it to upgrade the heros armor/damage/range when the blacksmith finishes researching the upgrade. I have set up each hero so that it accepts the upgrade. The code i am using is below. Any idea why it will not upgrade?

Blue MD
    Events
        Unit - A unit owned by Player 1 (Red) Finishes an upgrade
    Conditions
        (Researched tech-type) Equal to Medium-Density Ammo 
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (Current research level of Medium-Density Ammo  for Player 1 (Red)) Equal to 1
            Then - Actions
                Player Group - Pick every player in Team1 and do (Actions)
                    Loop - Actions
                        Player - Set the current research level of Medium-Density Ammo  to 1 for (Picked player)
            Else - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (Current research level of Medium-Density Ammo  for Player 1 (Red)) Equal to 2
                    Then - Actions
                        Player Group - Pick every player in Team1 and do (Actions)
                            Loop - Actions
                                Player - Set the current research level of Medium-Density Ammo  to 2 for (Picked player)
                    Else - Actions
                        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                            If - Conditions
                                (Current research level of Medium-Density Ammo  for Player 1 (Red)) Equal to 3
                            Then - Actions
                                Player Group - Pick every player in Team1 and do (Actions)
                                    Loop - Actions
                                        Player - Set the current research level of Medium-Density Ammo  to 3 for (Picked player)
                            Else - Actions
                                Do nothing

As far as i can tell this trigger SHOULD work, but it doesn't, any help appreciated.

Don't use Trigger, Is simple.
Create the upgrades in Object Editor.
Edit the hero for use the upgrade created "Techtree-Upgrades used".
And edit a blacksmith for ability the upgrade researchs "Techtree- Researchs Avaliable"
Finish

yea i did that, but then it only upgrades for the owner of the blacksmith. Im trying to get it to upgrade a whole team.

You need for team of player that gave upgrade?

I need it so that when a player on team 1 researches an upgrade it will upgrade all units owned by players on team 1.
