I have downloaded a LaTeX titlepage template from here and modified it for my own use. However I seem to have inadvertently changed the line spacings for the template, and now there is an error in the code:
\begin{titlepage}
\drop=0.1\textheight
\centering
\vspace*{\baselineskip}
\rule{\textwidth}{1.6pt}\vspace*{-\baselineskip}\vspace*{2pt}
\rule{\textwidth}{0.4pt}\\[\baselineskip]
{\LARGE Title Page\\ [0.3\baselineskip] Errors}\\[0.2\baselineskip]
\rule{\textwidth}{0.4pt}\vspace*{-\baselineskip}\vspace{3.2pt}
\rule{\textwidth}{1.6pt}\\[\baselineskip]
\vspace*{2\baselineskip}\\[\baselineskip]
{\Large Xylius\\
Chemistry\par}
\vspace{1cm}
{\itshape Dr. X\par}
\vfill
{\scshape 01/01/2017} \\
\end{titlepage}
Can anyone help me out as to find where the error is?
Thanks in advance
