Board Game Arena

So my group has tried starting Homesteaders twice, and we cannot for the life of us figure out how to pay money for auctions? Can anyone please describe how exactly that part of the interface works.... thanks!

To specify---what needs to be clicked on to confirm our auction payment. We would all start with 7 silver, and even if we won an auction for $3, and had a wood to pay for a building, we couldn't get the game to advance. It would say that someone needed to pay for their auction, and we couldn't figure out what to click on to actually pay for it.

you would click the "Pay: 3(silver)" button. then you would pick your building.
