Color Adjustment - Not Effecting Color Selection

Question

I could use some help doing color adjustment. I'm using the Color adjuster to adjust the grass in one of my photos from Green to Yellow. When I do this, some of the blades of grass are still staying Green. I added another color adjustment and selected one of the Green blades of grass with the eye dropper tool. Unfortunately when I try to adjust it, they stay the same color (green).
Am I doing something wrong? I thought the eye dropper would be able to select the green I'm trying to adjust, so I can adjust it's Hue.

Hmmm...
Have you tried to expand the range parameter? Try pushing it all the way up to the max to see if you can make this adjustment have some sort of noticeable effect. You can, in fact, overload this parameter by typing a value greater than '2' into the value box - the maximum in this case seems to be '20'. (You can always pull it back or even reset it to '1.00' if required.)
Failing that, try and make a test adjustment in, say, the water - in the bright patch at the right. I reckon it has a hue of about 215º to 200º. Sample it and push each parameter all the way to the right. This should give it a distinctive bright purpley/pinky cast. If this doesn't work for this image, then there's something fundamental we're missing here.

PS No, I don't simply look at an image and say that such-and-such an area has a hue of about 68.4º - I pulled your screenshot into Aperture and tinkered with it!
