What is wrong with my trigger?

[Wardonis]

Max mana level:
Events
Unit - A unit Finishes an upgrade
Conditions
(Researched tech-type) Equal to Max mana
Actions
Set maxmana = (maxmana + 1)
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
maxmana Greater than or equal to 5
Then - Actions
Unit - Change ownership of Father Mazon 0186 <gen> to Player 6 (Orange) and Change color
Custom script: call DestroyTrigger( GetTriggeringTrigger() )
Else - Actions
-------------------------------------------------------------------------------------
Before this trigger has a chance to run maxmana is set to 0 by a different trigger
--------------------------------------------------------------------------------------
I can't see any effects from it
