Programming :: Bash - Calling A Specific Variable Based On User Input?

I'm trying to call a specific variable based on a user selection. For example:

Code: Select a file:

[1] foo.tar
[2] bar.tar

Enter a selection: I have already coded each possible selection to have its own variable. If the user selects 2 I need to select $SELECTED_TAR2, or if they select 1 I need to select $SELECTED_TAR1 and then do something like this behind the scenes:

Code: cp /home/user/$SELECTED_TAR2 /home/user/backup/$SELECTED_TAR2

I was thinking something like this:

Code: echo "Enter a selection: "
read -e SELECTED_NUMBER
cp /home/user/$SELECTED_TAR$SELECTED_NUMBER /home/user/backup

[code]....
