How to get two different types of Sections in one document

So basically I need to have two different section headings; one that is alphanumeric (A, B, C…) and one that is labelled like Experiment #1, Experiment #2, etc.

So far I found this solution that was helpful for the alpha sections. https://stackoverflow.com/questions/2839647/latex-how-to-change-one-of-section-numbers-to-a-custom-letter

This is what I’ve tried:

documentclass[titlepage]{report}



newcounter{alphasect}
defalphainsection{0}
newififalphainsection

letoldsection=section
defsection{%
  ifalphainsection
    addtocounter{alphasect}{1}
  fi%
oldsection}%

renewcommandthesection{%
  ifalphainsection% 
    Alph{alphasect}
  else%
    arabic{section}
  fi%
}%

newenvironment{alphasection}{%
  ifalphainsection%
    errhelp={Let other blocks end at the beginning of the next block.}
    errmessage{Nested Alpha section not allowed}
  fi%
  setcounter{alphasect}{0}
  alphainsectiontrue
}{%
  setcounter{alphasect}{0}
  alphainsectionfalse
}%

%This is for Experiment Sections to be numbered as "EXPERIMENT #__"


newcommand{experimentarabic}{EXPERIMENT #arabic}
newcounter{expsect}
defexpinsection{0}
newififexpinsection

letoldsection=section
defsection{%
  ifexpinsection%
    addtocounter{expsect}{1}
  fi%
oldsection}%

renewcommandthesection{%
  ifexpinsection% 
    experimentarabic{expsect}
  else%
    arabic{section}
  fi%
}%

newenvironment{expsection}{%
  ifexpinsection%
    errhelp={Let other blocks end at the beginning of the next block.}
    errmessage{Nested exp section not allowed}
  fi%
  setcounter{expsect}{0}
  expinsectiontrue
}{%
  setcounter{expsect}{0}
  expinsectionfalse
}%

begin{document}
title{Title}
author{Author}
date{Date}
maketitle
tableofcontents


begin{alphasection}
section{First alpha section}

section{Second alpha section}

section{Third alpha section}
end{alphasection}

setcounter{section}{0}
begin{expsection}
section{First Experiment section}

section{Second Experiment section}

section{Third Experiment section}
end{expsection}


end{document}

I basically just tried to do the same thing to set up a new environment and then I can reset the section counter when starting my Experiment #_ sections.

This code doesn’t work though, and it was important for me to have the sections not just be section*(Experiment #1...) because I need them to show up in the ToC, and not setcounter{secnumdepth}{0} because I need figures and equations to be like "Figure 1.1" for Experiment #1.

Hopefully somebody sees my error or has any better ideas to get this. Thanks!

EDIT: For some reason both the alphasection and expsection work when I comment the other out. They don’t work together for some reason. Also the ToC for the Experiment #_ sections are super squished.
