I have tried equipping a unit with two pistols with Darth Duck's double pistol animation, but it won't work, same for the underhand chaingun made by Caleb. I tried replacing the common pistol odf animation with the double pistol animation but the game would just crash. So can anyone help?

not without an error log

Oops I meant the chaingun crashes, not the double pistol. I put the double pistol animation in the unit's odf but the unit won't have the second pistol in the left hand. With the chaingun I put the gunner animation in both the unit's odf and the common chaingun odf, the chaingun would be in the correct position in the spawn list but when I try to play the unit, the game crashes. Here's what I typed in the unit's odf: and the common chaingun odf: And the double pistol animation (I'm temporarily using the rifleman): EDIT
Here's the error log (the end of it really):
