Problem loading functions in ZSH

[dustpyle_x2]

I have a file called precmd in ~/.zfunctions that contains

echo "hello"

My zshenv file should automatically autoload this for me, but it doesn't seem to be working. Why is this? (~/.zshenv below)

## set debug variables
debug="echo"
debug=":"

## set default zsh config directory
export ZDOTDIR=$HOME

## source .zshrc if it exists
if [[ -r $ZDOTDIR/.zshrc ]]; then
	source $ZDOTDIR/.zshrc
fi

## set env-ariables
export PS1=$'%{\e[0;32m%}%U%n@%m%u:%~%(!.#.$)%{\e[0m%} '

## add ~/bin to path should it exist
typeset -U path
if [[ -d $HOME/bin ]]; then
	path=($HOME/bin $path)
fi

## add directories for custom functions
typeset -U fpath
fpath=(/etc/zsh/functions $ZDOTDIR/.zfunctions $fpath)

## autoload all the files in all the directories of fpath that are not empty
$debug -e "\nlooping through dirs in fpath\n"
for dir in $fpath; do
	$debug -e "\nif dir isn't empty...\n"
	if [[ $((`ls -a|wc -l` - 2)) -gt 0 ]]; then
		$debug -e "\nautoload functions\n"
		for func in `ls -a $dir`; do
			[[ ! -d $dir/$func ]] && autoload $func && $debug "autoloading: $func"
		done
	fi
done

'precmd' gets printed yet I don't get a nice little 'hello' before every prompt why is this?

Update:
Ok, it is working. When I open the terminal the functions have been autoloaded and I get a nice little 'hello' before each prompt. Problem is if I change it to goodbye and type source ~/.zshenv nothing changes, but if I close the terminal and start a new one, it works. How do I fix this?
