Ok, the first thing is you need to post the complete script. You're missing the top of the script since I don't see the #!/bin/bash line.

Next is use the code tags to enclose your script to make it easier to read. Hard to say if an error is due to transcription or just because the software is deleting spaces and brackets.

Next is the Main_Menu function is not right. You have the while, do and clear outside of the function instead of inside.

Next is you aren't echoing the menu options.

The Volume_Date_Returns function has some bogus if statement constructs. They're commented out but they should be corrected if you're going to use them.

The rest looks basically ok. I'm not 100% sure on how you're using if statements. I'm pretty sure you need to use brackets to enclose the test. I always do and like to verify it before saying it for sure. Can't hurt to actually enclose in brackets though.

Fixed Main_Menu:

Code:

tapemgr_Main_Menu()
{
  while : do
  clear
    echo " Tape Management System Menu"
    echo "This system is used to report Legato ERV Offsite and Tapes Returned"

    echo "1. BUR IPS Tape Offsite Report"
    echo "2. BUR IPS TAPE Returns from ERV"
    echo "q. Quit or Ctrl-C"
    echo "Select an option 1,2,q"
    read option
    case $option in
      1) Tapes_Offsite_Menu();;
      2) Tapes_Return_Menu();;
      q) exit;;
    esac
  done
}

script

SCRIPT(1)						    BSD General Commands Manual 						 SCRIPT(1)

NAME

     script -- make typescript of terminal session

SYNOPSIS

     script [-a] [-f] [-q] [-t] [file]

DESCRIPTION

     Script makes a typescript of everything printed on your terminal.	It is useful for students who need a hardcopy record of an interactive
     session as proof of an assignment, as the typescript file can be printed out later with lpr(1).

     If the argument file is given, script saves all dialogue in file.	If no file name is given, the typescript is saved in the file typescript.

     Options:

     -a      Append the output to file or typescript, retaining the prior contents.

     -f      Flush output after each write. This is nice for telecooperation: One person does `mkfifo foo; script -f foo' and another can super-
	     vise real-time what is being done using `cat foo'.

     -q      Be quiet.

     -t      Output timeing data to standard error. This data contains two fields, separated by a space. The first field indicates how much time
	     elapsed since the previous output. The second field indicates how many characters were output this time. This information can be used
	     to replay typescripts with realistic typing and output delays.

     The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if ignoreeof is not
     set) for the C-shell, csh(1)).

     Certain interactive commands, such as vi(1), create garbage in the typescript file.  Script works best with commands that do not manipulate
     the screen, the results are meant to emulate a hardcopy terminal.

ENVIRONMENT

     The following environment variable is utilized by script:

     SHELL  If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
	    shells set this variable automatically).

SEE ALSO

     csh(1) (for the history mechanism), replay(1).

HISTORY

     The script command appeared in 3.0BSD.

BUGS

     Script places everything in the log file, including linefeeds and backspaces.  This is not what the naive user expects.
