getting error when trying to use tikz

[quiet lynx]

As above says, not entirely sure what’s going wrong, don’t understand the error message sorry, images attached

on line 2 you said "on grid" but it doesn't understand what that means

Ok so this is smth my professor is trying to do, he’s just been getting into discord but knows latex and I’m not entirely sure what this is but he’s not on this server so I offered to ask, any idea what he’s trying to do with on grid and how he could fix it? Sorry for the trouble lol

[real lance]

I think you need to use the positioning library

,texdoc tikz

For future reference, you should copy and paste the codes instead of just sending pictures.
