echo $path returns blank on Mac

Question

echo $path is returning blank for me. The following are contents of my .bash_profile.

CHANGE PROMPT
export PS1="►►"
export TERM=xterm-color
export GREP_OPTIONS='--color=auto' GREP_COLOR='1;32'
export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad

#PATH
#export PATH="/usr/local/sbin"
#export PATH="$PATH:/Library/Developer/CommandLineTools/usr/bin"
#export PATH="$PATH:/Users/suraj/Scripts"
#export PATH="$PATH:/Users/suraj/Library/Mobile Documents/com~apple~CloudDocs"

Notice that I have commented out the path lines but echo $path still returns blank if I uncomment them.

Solution

Path needs to be in all caps ie $PATH. Bash is case sensitive.
