Looping in Bash: syntax error: unexpected end of file

Im new to to this Bash/Shell stuff and got to do some network analysis for a uni assignment.

Just trying to do a simple loop but getting a weird error that have been unable to fix despite a 2 hour google crawl:

#!/bin/bash
x=1
while [ $x -le 5 ]
do
  echo "Welcome $x times"
  x=$(( $x + 1 ))
done

I have tried using a for loop using the following syntax:

#!/bin/bash
for i in {1..5}
do
   echo "Welcome $i times"
done

Whenever I place the first script on my server I get the following message:

./temp.sh: line 8: syntax error: unexpected end of file

Before running this file I have performed the following commands to add permissions and make the file executable:

ls -l temp.sh
chmod +x temp.sh

Just as a side note I found the following stackoverflow question about loops, copied the 'fixed code' and got the same error: Looping a Bash Shell Script

Im running version 4+ and using G-VIM as the text editor on Windows 7. Anyone got any ideas?

MANAGED TO SOLVE THIS MYSELF:

Seeing as my reputation is still too low I can't answer this myself at present so to stop people wasting there time here is how I fixed it:

Ok i've managed to fix this so will leave this up for anyone else who looks around.

My problem was that I was using FileZilla to connect to my server. It seems that even though I was using WinVi or G-Vim to create the files FileZilla was adding some form of extra characters to the end of my file when I transferred it to the server as im running Windows.

I switched to WinSCP as my connection agent and tried it and hey presto worked fine.

Thanks for the other answers.
