C程序使用结构发生了什么？/无法正常工作

I'm currently working on fixing a piece of code I've been working on for the past few weeks. Pretty much what this is supposed to do is generate a linked list of structs. Currently it generating nothing but I'm still working on the code. I could use any advice on how to implement the insert_ordered correctly. Thanks!I'm currently working on fixing a piece of code
