nothing shows up! no image or error?

Albert,

For each layer it's important to tell mapserver which projection your 
data is stored in. In your case:

LAYER
...
PROJECTION
"init=epsg:26914"
END #PROJECTION
END #LAYER

The epsg code 26914 represents "NAD83 / UTM zone 14N". I think that's 
what you're looking for.
