Levels command problem

[ppera2]

I get syntax error message when try this:
Levels 0,1.3,240,17,255 (or any other values).

It's all by documentation... What is problem ?

Unclear Documentation!
the numbers have to be in brackets
Levels (0,1.3,240,17,255)

Thanx... it works now.

Funny thing is that I tried with brackets, but it looks that I mistyped or made other error, cause it worked not so.
