What steps will reproduce the problem?
1.Create a shop sign with:
[lpb]
16x250x16
$600.00
stone

or a sign:

[lpb]
16 x 250 x 16 (spaces between the number and x)
600 (no decimal and no money sign)
stone

What is the expected output? What do you see instead?
I expect it to create a shop.  Instead, it says, "[Libelula PB] The shop you are trying to create has invalid values" and puts a line through the numbers.

What version of the product are you using?

v2.0.10 Release

Do you have an error log of what happened?
The server log does not report anything.

Please provide any additional information below.
Craftbukkit version git-Spigot-5f38d38-18fbb24 (MC: 1.8.8)

The signs don't seem to work with even numbers.

The signs have to specify odd numbers so in your case 15 249 15 (this is to account for the block being in the center)
