I could use some help with getting the tech tree editor to work for me.  I am wanting to add a tech that would give a additional bonus to Soldiering.  I want it to be a branch off of Planetary Invasion.  I believe that I have most of it worked out.  But when I go to save the change.  I get the Parameter Incorrect message.  I am wondering if I am using the wrong Internal name.  I am wanting this to be on the Minor Tech tree in ToA.  I have tried to follow what i can see in the Tech trees in the game.  But am at a loss as to what Parameter is wrong.

This is how I have it set up:

Internal Name:  Weapons

Display Name:  Battle Suits

Required Tech:  Planetary Invasion

Required Alignment:  None

Group Name:  None

Model:  Nanometal 0

Branch Name:  Weapons

Category:  Invasion

Civ Ability Bonunes:  Soldiering +20

Trading:  yes and at 30

Creative Ability:  yes

Stealing:  yes

I also have the short and long descriptions.

Research cost:  900

AI value:  12

I would appreciate any advice you can give me.
