Knight editing problem

[SasaV]

I am trying to add a new weapon to the knight model(or rather bandit lord model, but it's almost the same ), but the sword i added doesn't appear on any of the animations of the knight, except on the death animation . I put my 2 swords in the same places where the original 2 swords were, and i made them move with the left hand. Can someone please help me fix this problem? Or, if it's not that easy, can someone please show me how to edit this model?

EDIT 1: I figured out that it had something to do with the geosetanims: i put 1 each for my swords and i also figured out that 1 means the mesh appears and 0 means the mesh doesn't appear in that animation. So i put 1 everywhere except at the decay bone and I put 0 at the decay bone. When i try to see the result, nothing changes.... Maybe it has something to do with the material or bones? Please help me someone...

EDIT 2: problem fixed.... could a mod please delete this thread?
