Cant make clipping mask

[smooth_Moon8473]

Same old, same old.

I'm new to illustrator, but seem to be having the usual problems with clipping masks.

I just want to crop one corner of an image so it is curved. It feels like this should not be so ridiculously hard, and I honestly don't understand why programmes only allow square crops of images. Anyway:

- I have uploaded my image

- I have drawn the shape I want for a clipping mask (rectangle with one corner curved)

- I have positioned that shape over my image

At that point, I was getting the error message 'can't create mask, more than one object must be selected'.

I looked through this community and found that I had not made my mask shape a compound path.

I corrected this.

Now, I just get the error 'can't make clipping mask'.

I just don't see what I am doing wrong- the image is below the shape, both are selected, the shape is a compound path.

Please please can anyone help?

If it's just one path, it doesn'T need to be a compound path. Please show what's in the layers below.

smooth Moon,

It looks as if:

You (may) have the image on Layer 1, maybe with something else, and something on Layer 1 is selected, maybe only the image.

You have nothing selected on Layer 2, where you (presumably) have a Compound Path, which may consist of the original rectangle and a smaller rectangle less a quarter circle, so the Compound Path may be the parts you wish to exclude from the Clipping Path/set.

What appears/happens if you Expand Layer 1 and release the Compound Path in Layer 2 and Expand that as well if needed?
