bash script fails with commands

Question

I have the following script

#!/bin/bash

VERSION=2020-12-R1
LINK_LIBRERIA=https://github.com/greatscottgadgets/ubertooth/archive/refs/tags/$VERSION.tar.gz
LINK_UBERTOOTH=https://github.com/greatscottgadgets/ubertooth/releases/download/$VERSION/ubertooth-$VERSION.tar.xz


LIBRERIA=libbtbb-$VERSION.tar.gz
## Instalacion de las librerias


SUCESS=1
while [ $SUCESS -eq 1 ]
do
  echo "Select Instalation Directory, left EMPTY for use the actual directory"
  read PATH

  if [ -z $PATH ] 

  then
      PATH=$( pwd )
  fi

  cd $PATH
  SUCESS=$?

done

sudo apt-get -y install cmake libusb-1.0-0-dev make gcc g++ libbluetooth-dev \
pkg-config libpcap-dev python-numpy python-pyside python-qt4 -y

# wget $LINK_BASE_LIBRERIA -O $LIBRERIA
# tar xf $LIBRERIA

When I run it it prompts this:

./main.sh: line 29: sudo: command not found

This probles is the same with the commented commands wget and tar

The ugo priviledges are:

$ ls -l
total 12
-rw-rw-r-- 1 k1k4ss0 k1k4ss0 1064 Mar 27 18:21 LICENSE
-rwxrwxrwx 1 k1k4ss0 k1k4ss0  726 Mar 28 12:31 main.sh
-rw-rw-r-- 1 k1k4ss0 k1k4ss0   81 Mar 27 18:21 README.md

I've tried almost all, but i don't known why, I've searched in internet and look for some scripts with similar commands within, but the problem persist.

The problems as said in the comments by @Jetchisel is the PATH variable, the interpreter confuses it with the PATH of the global variable, changing it to lowercase solves the problem
