Issue with shell script: not detecting file properly

The following script is meant to check the presence of a file - called filename0.94.tar.gz - and uncompress it:
Code:
#!/bin/sh

# check presence of file
VERSION=0.94
if [ ! -f filename$VERSION.tar.gz ]; then 
  # file not present: abort
  echo "Files cannot be found."
  #exit 1 (commented out this line, so we can see how the rest of the program behaves)
fi
# uncompress file
echo "filename: uncompressing latest version..."
tar zxf filename$VERSION.tar.gz

exit 0

The output is however:
Code:
Files cannot be found.
filename: uncompressing latest version...
tar: Error opening archive: Failed to open 'filename0.94.tar.gz': No such file or directory

This script is run in the same location where filename0.94.tar.gz is. Why does the script not detect the file and uncompress it? Manual uncompression works as intended.

Code:
if [ ! -f filename${VERSION}.tar.gz ]; then

I do not know what shell you have - try this to begin with.
