It looks like you're masking something rather than creating a shape.
Basically if you have a layer selected and then you go up and use the shape tool it's going to mask the layer you have selected.
Unless you have the STAR (SHAPE) icon active and not the mask icon, in which case it's going to create a shape within the selected layer.
Your best bet is to create a new shape layer then draw out your shape.
Assuming of course you have the fill function activated.
A screenshot of your interface would be helpful so we could see what you have selected and so forth.
Google how to grab a screen capture of your monitor.
There's no reason you should be taking a photo of your screen with a camera, after all you are learning how to do motion graphics/video editing right?

Are you using a gradient fill?
Yes, that's what the problem was. I checked color fill and it fixed that. Thank you so much for your help! I'm in a little deep here haha.
