Upgrade house level 2

I have the quest to update the house to level 2.

If I click the house it does nothing.

If I click the build icon button on the bottom it shows the house screen. There are 3 house pictures, 2 displayed and the third with a chain. It says something like 50 gold and 10 wood. I have these but the upgrade button at the bottom is not enabled.

I am wondering if I do not have the right kind of wood?

Any help would be appreciated. I am stuck here. Thanks.

Hi, got it. I had to take the wood to create planks.

The graphic is very confusing. It looks like gold and logs are needed (on the left) but there are are also 2 graphics on the right - a level 2 house and planks. This is not a real obvious display. but got it now.
