Ledger item purchase button greyed out

[SalgoudTF]

What does it mean when restocking purchases for provisions, weapons, and medicine are greyed out in the camp ledger. The icons for these at the top right are yellow by the way. Adequate funds are available to purchase these restocks. In fact, when I get to the first item, the purchase button can be pressed, but it doesn't complete and then greys out. The text box says send someone to town to purchase what is needed. Is that something Arthur has to set in motion? Does he have to send someone and if so, how.

You likely need whoever gets said supplies to get the supplies. Talk with people in the camp. You'll eventually find who you need to talk to.

Thanks for the suggestion, SNAK3S! Sorry about the late reply.
