# How to insert new slide with < > tag

I am new to beamer. Here in this case <7-> is not creating new slides rather that <6-> prints the ABC5 and ABCBLOCK together. What is the possible solution if I want separate slides for ABC5 and ABCBLOCK. And also in place of <7-> there is a weird sign which I can't explain what it is.

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usepackage{bookman}
\usecolortheme{beaver}
\usepackage{utopia}

\title[abc]{Abc}
\author{M.X\inst{1}}
\institute{
\inst{1}
Department Of CSE\\
X University
}

\date{20 June, 2017}

\begin{document}

\begin{frame}
<1->
\frametitle{Examples}
\begin{itemize}
\item <2-> ABC1.
\item <3-> ABC2
\item <4-> ABC3
\item <5-> ABC4
\item <6-> ABC5
<7->
\begin{block}{Disclaimer}
ABCBLOCK
\end{block}
\end{itemize}

\end{frame}

\end{document}

• Note: How things are named is a bit counter intuitive when you starts with beamer, but you should have a look to the user guide to understand the difference between slides (linked to a "page number") and frames (linked to a "pdf page"). You also have tutorials that are really informative. – ebosi Jun 20 '17 at 15:19

Your issue is due to the <7-> that should be positioned right after \begin{block}.
For more details, see beamer user guide on section 9.4 Environments with Overlay Specifications. In Section 12.3 Block environment, it is also stated that the correct syntax for block environments is:

\begin{block}<⟨action specification⟩>{⟨block title⟩}<⟨action specification⟩>
⟨environment contents⟩
\end{block}


You should thus modify your code as following:

\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usecolortheme{beaver}
\begin{document}
\begin{frame}
\frametitle{Examples}
\begin{itemize}
\item <2-> 2
\item <3-> 3
\item <4-> 4
\item <5-> 5
\item <6-> 6
\begin{block}<7->{Disclaimer}%<------- look here!
7
\end{block}
\end{itemize}
\end{frame}
\end{document}

• Thank you for your help. It works like a charm and I understand the concept of writing < -> syntax – Maruf Jun 20 '17 at 15:35
