try putting quotes around the backticks like :

every variable you have is giving the same error, that's a clue to the issue.

most likely your login id is defined as csh, and you did not define your "shebang line" as sh or ksh on your script, so it assumes csh syntax when you try to run the script. might want to google shebang line and read up on how to create a script vs. a file with commands.

insert at first line:
#!/usr/bin/ksh ( or whatever your path for ksh is; which ksh to locate correct path).
