Problem while traversing directories

I was given to create a backup of all files in a given directory(command line argument) into say /home/vishal/back and the back up files must be accordingly to the extension of the file i.e pdf files are saved in back/pdf doc files back/doc etc . I gave a recursive function to traverse through the given directory but im getting correct answers until this case exists

say the user gave user/yyy and lets say directroy yyy contains 2 directories xxx and zzz and one file say op.doc. If say xxx has 2 other directories and also some file,(there is no error when there is only directories and no file ). Here is my code ... please help


recur() <<<<recursive function>>>>>
{
echo $1
cd $1
for i in *
do
if [ -d $i ]
then recur $1/$i

else
filename=$i
extension=$(echo ${filename}|awk -F\. '{print $2}')
cd /home/vishal/back
count=0
for p in *
do
typ=$(echo ${p})
if [ $extension = $typ ]
then count=1
break
fi
done


if [ $count -eq 1 ]
then cp $1/$filename /home/vishal/back/$typ/
else
mkdir /home/vishal/back/$extension/
cp $1/$filename /home/vishal/back/$extension/
fi

fi

done
cd $1
cd ..
}

recur $1 <<<<$1 is user given directory>>>>>>>
