[HELP] Curve's will not fill properly.

unlike how i’ve seen in many tutorials when i have a shape i’ve made with curves within another shape i made with curves, i cant seem to make the inside of the object clear. imagine the image like a triangle doughnut except when i try and fill, the entire thing fills, even the middle. I’m not stuck in wire frame mode, and all the curves are closed… What could be wrong?

Check you haven’t any points on the curve too close to each other or are overlapping.
Difficult to tell without seeing your blend. You can post your blend file here

Are both of your curves the same object, meaning did you add the second curve in edit mode? Are they both 2D curves? These are the two main criteria that have to be met for it to work.
