Nathan Bubna commented on VELOCITY-542:
---------------------------------------

This is because '-' is a valid character in a reference.

Try  doing #set( $thisCampNumber-1 = "hello world" ) before running your test.

>             Project: Velocity
>          Issue Type: Bug
>          Components: Engine
>    Affects Versions: 1.5
>            Reporter: Will Glass-Husain
>            Priority: Minor

> The following example:
> #set($thisCampNumber = 10)
> #set($nextCampNumber = $thisCampNumber+1)
> #set($previousCampNumber = $thisCampNumber-1)
> #set($previousCampNumberB = $thisCampNumber - 1)
> 1: $thisCampNumber<br>
> 2: $nextCampNumber<br>
> 3: $previousCampNumber<br>
> 4: $previousCampNumberB<br>
> produces this result
> 1: 10
> 2: 11
> 3: $previousCampNumber
> 4: 9
> Note that using a minus sign in a #set statement does not work if there are no spaces around it.  (however, the same is not true for +).
