I just started to learn how to work in Overleaf, so I'm still such a noob. Anyways, I'm doing a project for my class and I don't know how to fix the "missing $ inserted issue". The converted code does look how i want it to look, but the error bothers me. I will be really grateful if somebody can help me. Here is my code:

\documentclass[20pt,,margin=1in,innermargin=-4.5in,blockverticalspace=-0.25in]{tikzposter}
\geometry{paperwidth=42in,paperheight=32.5in}
\usepackage[utf8]{inputenc}
\usepackage{graphics}
\usepackage{multicol}

\title{Exercise}
\date{October 2022}


\begin{document}


\begin{columns}
%COLUMN 1
\column{0.30}
%Block A
\block{\Huge Why participate in one?}{


\vcenter{{\hbox{\includegraphics[width=5cm]{icon1.png}}}}
\huge \textsl{ Meet new people}


\vcenter{{\hbox{\includegraphics[width=5cm]{icon2.png}}}}
\huge \textsl{ Build your resume}}


\end{columns}


\end{document}

my code

  • Welcome to TeX.SE. If you highlight your code while editing and click {}, it will become properly formatted (we've done this for you). You're right to be bothered by the error: it means that you lucked into getting the output you wanted. I'm not finding a {columns} environment nor a \column command in the multicols package. What are you aiming to do with that? – Teepeemm Oct 28 '22 at 19:58

    Where did you find \vcenter? It can only be used in math mode. Remove it. But using \hbox is not LaTeX. – egreg Oct 28 '22 at 19:58
  • Your document source is over-complicated. Moreover, your bad luck is that you are using LaTeX which sets \errorcontextlines to zero. So, you don't see the crucial part of the error message: <to be read again> \vcenter. If you see this then you can resume that \vcenter is the problem outside the math mode and TeX starts math mode inserting $. Of course, \vcenter can be used only in math mode, because this primitive has to know the placement of math axis: the vertical centering is done around math axis. – wipet Oct 28 '22 at 20:12
  • Sounds like you want vertical alignment - Vertically center text on a page - TeX - LaTeX Stack Exchange. Basically just don't "randomly guess" LaTeX commands and you should be mostly safe. – user202729 Oct 29 '22 at 02:12
