Wentworth auction Buying/Bidding problem

hello ive tried to buy aswell as tried to sell an item in the auction house ..
But the problem is that im unable to make a bid for anything
i cant sell either..
when i try to enter a bid or just try to put in a digit..it doesnt come up. the field where it says 'ENTER BID' is grey and im unable to type a thing in there....

Ive checked that i have enough Influence and i do...
ive checked that my salvage has space and it does..

is there somthing ive missed?
do i need to go through a tutorial to unlock it?
helppp helpp
