# Undefined Control Sequence?

I have a problem while practicing latex here. Actually, I am newbie in using this application.

I found

Where my code is here :

Does anyone know what the matter here ? And what should I do to make it fix ?

• The command for the \LaTeX logo is \LaTeX, not \Latex. – Bernard Jun 28 '15 at 15:30
• \maketitle is after \begin{document} – juanuni Jun 28 '15 at 15:30
• Besides what Bernard said, you need an explicit space \LaTeX\ Document; othersise, Document will appear with no space after the logo. – Gonzalo Medina Jun 28 '15 at 15:34
• Could you post a minimal example illustrating the problem (fully compilable)? – Bernard Jun 28 '15 at 15:57
• Can you recheck the case of the letters L, T and X in \LaTeX? Those three letters all have to be upper case. – Nicola Talbot Jun 28 '15 at 16:20
