Can't open the .txt file!

So, I have the read function to my file set up, but every time I run the program to read the file it will not open, and it displays: "File not open". What am I doing wrong?

Are you sure that the folder c:\desktop\ exists?

Yeah, so I altered the destination upon realization that it didn't exist, but now I get this:

...................................
Name........
Street......Press any key to quit...
