adjustment Layer's mask properties

Latest version of PS. I have a curves adjustment layer with a mask.  Double click the mask and in properties I lower the opacity.  Whilst in the properties the image shows the reduction correctly.  I click OK but it doesn't take effect.  To confirm this I upped it to 100% - no difference in the image.  I then reduced it to 0 but still no effect in the image.

You are talking about 'Opacity', but the layer mask properties panel does not have an Opacity slider. It has a Density slider, but that is not the same. The Density slider will only effect the blacks in a mask, so you you can't make the default white mask of an adjustment layer (partly) transparent by lowering the Density slider. Could that be the problem?

OOPS!  Sorry, yes I meant density.   I am following a tutorial...   "Make a Curves adjustment layer for the model and lower the brightness. On the layer mask of Curves, erase the effect as shown to keep this part brightened because it is reflected by the light coming from the forest."  

So I have painted black on required areas of mask.  Double click mask and lower density.  Whilst it effects the image in the properties, after clicking ok, the image itself isn't changed.   I tested it with 100% and 0% density but there is never a change on the image.  Hope that makes sense!

It doesn't make sense as long as I can't see the image and the mask panel. You don't have to double-click the mask, just selecting it with a single click should be enough. And there isn't an 'OK' to click in the properties panel either, so I still wonder what exactly you are doing. Here's two screenshots that show it works as expected for me. I used a B&W adjustment layer so it's easier to see.

OK, I see the problem now.  He was incorrect saying double click on mask.  If I double click on the mask I get the following, which is where I got opacity from!!

That is the 'Select and Mask' interface. The opacity slider has nothing to do with the opacity of the mask itself, but with the view you selected in the circle.
