Problem with Recursive function

Hi all,

I have to move all the files in a tree directory structure to a single directory. Inorder to know which file is from which directory , i'll have to add the name of the directory to the file name. For this i wrote a recursive function which is as follows
---------------------------------------------
datamover()
{
cd $1
#OLD_DIR=$2
for i in *
do
if [ -d $i ]
then
TMP_DIR=$i
datamover $TMP_DIR
echo $i
else
mv $i ../$1_$i

if [ -f $1/ ]
then
echo some files still exist
else
cd ..
rmdir $1
fi

fi
done
}
----------------------------------------------------------------
When ever I execute the same on a directory structure as
DirA --> DirB --> DirL -->fileN
--> DirM-->fileO
--->DirC --> DirP-->fileR
--> DirQ-->fileS

the program is giving the output as follows
DirA -->DirB -->DirL_fileN
-->DirM_fileO
--->DirC --> DirP-->fileR
--> DirQ-->fileS

and the debug ouptut is as follows
------------------------------------------------------
+ echo Dir Name is DirA
Dir Name is DirA
+ MAIN_DIR=DirA
+ datamover DirA
+ cd DirA
+ '[' -d DirB ']'
+ TMP_DIR=DirB
+ datamover DirB
+ cd DirB
+ '[' -d DirL ']'
+ TMP_DIR=DirL
+ datamover DirL
+ cd DirL
+ '[' -d fileN ']'
+ mv fileN ../DirL_fileN
+ '[' -f DirL/ ']'
+ cd ..
+ rmdir DirL
+ echo fileN
fileN
+ '[' -d DirM ']'
+ TMP_DIR=DirM
+ datamover DirM
+ cd DirM
+ '[' -d fileO ']'
+ mv fileO ../DirM_fileO
+ '[' -f DirM/ ']'
+ cd ..
+ rmdir DirM
+ echo fileO
fileO
+ echo fileO
fileO
+ '[' -d DirC ']'
+ mv DirC ../DirA_DirC
mv: cannot stat `DirC': No such file or directory
+ '[' -f DirA/ ']'
+ cd ..
+ rmdir DirA
rmdir: `DirA': No such file or directory
--------------------------------------------------------------

Can anybody tell me wht's the problem with the code and how to correct it?
the output i require in this scenario will be as
DirA-->DirB_DirL_fileN
-->DirB_DirM_fileO
-->DirC_DirP_fileR
-->DirC_DirQ_fileS

Thanks in Advance
