i dont know what i did wrong the foot gets really messed up after i do the -12 offset

Make sure you offset all the relevant parts.
It looks like you have only done the foot bone, and not the toe and heel etc.

Yeah @Wayne! What took so long?
3 minutes, your slacking...

@puddles , I love your enthusiasm, you are obviously wanting to learn animation the best you can with some help and support from the community. It's a shame when someone has the potential but is a afraid to ask questions, maybe because their English ain't, sorry isn't good, or are embarrassed and don't want to look silly. I don't think you have any such problems and I applaud you for that.

I would like to offer you a couple of tips that may help you learn animation even better, and help you retain what you learn. We often see people complete courses with great results, but then struggle when they try to create a project of their own.

1. Watch the lesson through at least once before opening Blender to follow along. This helps to see little things that you may miss when following along. Like enabling something or changing a setting. It also helps to know where your heading in the lesson so you don't make the same mistakes the instructor makes, believe it or not they do make mistakes, not many, but it does happen. OK, maybe not mistakes, but they may change their mind on how to do something.

2. If you have an issue, try your best to resolve it first. Rewind the video a little, or even start from the beginning to see if you missed something. By doing this you train your brain to check for these things before you start and during your own projects. So many things in Blender are little things that need adjusting or something needs to be enabled. Even the instructors will spend hours/days/weeks researching and building a course before they even press record on the video. And even then the videos are edited.

3. Practice, practice, practice. You can never get enough practice. When you complete a course, or even a chapter or lesson, redo it but change it up a little. Maybe if you completed a walk cycle course, try a fast walk or a jog, or a stylized cartoon walk, imagine a clown with big floppy feet. 

I hope these little things help you with your Blender journey, you may already be doing them, but they maybe useful to some else.

Good luck with learning animation, you are doing great so far. I look forward to seeing some awesome animations from you in the future.
