You need to write this:

[Trade]
$1:
2 dirt:<amount of dirt you want to put in sign>


That should work if you put exactly that, but replace the bit in the <> with how much dirt you want in the sign :)

 

You would also need dirt in your inventory. In this case, it would need to be a multiple of 2. Sooo...
[Trade]
$1
2 dirt : 2 (Or any multiple of 2, as long as it's in your inventory)

watch this @CheezyMonkey21 oh, ond congtaz on resident, love the place you built in Cirrus!

 

It's all good @CheezyMonkey21 I updated rules anyway to 14 days, you can view the town thread here, it's updated. Also put a few things in your mailbox as a congratz for making resident thing (kinda whatever I had on me at the time). Also I'll come along and set up an erep box so if you have a tool that's about to break I can repair it for you if you put it in the box, which is safe because it'll be locked by you and I so no one can steal from it.
