I’m trying to figure out exactly what it is you are trying to do Berie and I’ve come up with this example. The image on the left has an ordinary drop shadow but the image on the right has an Inner Glow effect applied.
The second example shows the settings for the Inner Glow effect where you can change the size, colour and opacity of the effect. Apologies if I’ve misunderstood what you are looking for. Image from morguefile.

I'm afraid I didn't make myself clear. I'm trying to put a drop shadow around the inside edge of my photo.
I get the dropped shadow but it is too big and dark. I do click on the fx and it opens but is dimmed and clicking on it has no effect.
Any more suggestions?
It looks like you are trying to apply an Inner Shadow because you said you wanted the shadow to be around the inside edge of your photo. If so, . . . here is the explanation why those adjusting sliders are grayed out.
This is not a problem; it is by design. By default, when you open the Style Settings for the Inner Shadows, those sliders will be grayed out (deactivated). Just check mark the box(es) and now you can proceed to customize the settings.

I’m not sure what your goal is, but my favorite thing to do to soften the edges of a photo is to use 'inner glow'
In this case, I added a drop shadow and used the technique I mentioned earlier - I grabbed the shadow and pulled it out from under the photo - you can, of course, do that with the style settings menu, but I like to physically pull at it so I can see exactly what effect the change in shadow accomplishes while I'm doing it - instead of setting parameters and then having to do it all again, if I don't like the effect.
Now that I see this full sized, I don't much like the size of that inner glow (nor that framing effect), but this example does serve the purpose of showing what inner glow is. Choosing black as the inner glow color might accomplish a "shadow-type" look
