okay so background is ive got the normal stargates working fine except i want to make custom gate layouts that charge different prices. i dont want all stargates to charge infact i only want these certain gates to charge. im using iconomy and ive set the use iconomy in the config to true and when i place 'usecost=10' for example the gate works but doesnt charge/deduct cost.... heres my file layout

portal-open=8
portal-closed=0
usecost=50
toowner=true
X=49
-=49

any suggestions would be very appreciated as i cant find a thing elsewhere!
