Why: Bash syntax error near unexpected token `fi'

so the error I'm getting is syntax error near unexpected token `fi' on the second last 'fi'. Been scratching my head for a while about this. Any help is greatly appreciated! Thanks!

#!/bin/bash  

TFILE=/tmp/scripts/pdsh_demo.tmp  
if [ -f $TFILE ]; then  
   rm $TFILE  
fi  
/usr/bin/pdsh -R ssh -w host[0001-0200] 'command | grep -v "something"' >> $TFILE    

if [ ! -s $TFILE ]; then  
    exit  
fi  
if [ -f $TFILE ]; then  
    if grep -q "something" $TFILE ; then  
        grep -i "something" $TFILE | mailx -r "test.server" -s "Critical: something" -a $TFILE "test@test.com"  
    fi   
fi
