"if $dir isn't a valid directory" we say

if [ ! -d $dir ]
then
...

fi

thanks but that doesn't answer my question any other help would be great. remember if the input isnt ma directory then they are given the question do you want another try? if yes they have another go if no then it reloads the project again.

The first thing I can suggest is to make your code more organized. Just looking at this (with line numbers and all - even though we're missing the first 40-some lines) makes my eyes want to roll back in my head...
You can do it to fit your own style, but indenting can be your friend - for example:

(...)
read dir junk
if [ -d "$dir" ]; then
        echo "The \"$dir\" directory is valid."; cd $dir
        echo "You are now in `pwd`"
else
        echo "The \"$dir\" directory is not valid"
        echo "You are still in `pwd`"
fi
(...)
