Hi,
Works for me. Placing a "," rather that a "." decimal results in a
"expression invalid" so that can't be it. Are you really getting Nan?
Use the "value plugin" to look at this or look at the histogram in layer
properties. Sometime it is just the image scaling that is off. Send a
sample file to test if it's still an issue.
