Factions Money API

Hello everyone. I've encountered an issue attempting to use the factions API to access/set factions money balance. I've tried the following:

Code:

double monet = Money.get(mplayer.getFactionId());
double monet = Money.get(mplayer.getFaction());
double monet = Money.get(player);

All seem to throw this error:

Code:

Any help would be great, Thank you

 

Bump!

 

Seems to be an error on the API's side from what I can see, but I'm not the best at this type of stuff.

 

Hmm, Interesting I'll try an alternate version
