Why the compiler ignores the command \noindent?

Question

I am writing my master thesis on LaTeX. I should say that I had not used it before and everything is new for me. I was doing fine until I got some troubles when compiling the command \noindent and \hline.

I want my title page to end with an horizontal line at the bottom and the place where I am working and the date right above it. There is a very nice blank space from the supervisor's name to the bottom margin which the compiler just ignores and places the name of the city and the line in the next page. The frame of the page tells me that there is still space for placing text. Needless to say, I loaded the geometry with [showframe].

Moreover, I get an error message because of \hline which says >misplaced \noalign.

I had to modify the location of the vertical margin as well as the height of the body's box. Might that be the reason why the last line jumps into the next page?

This is cleaned up a very little. Note that I really have no idea what you are trying to do so I doubt very much that my answer will help you do it!
