When appending to variables it is best to encapsulate them with brackets {}.

i.e. instead of:
do:

/usr/sbin/adduser: line 95: syntax error near unexpected token `newline'
/usr/sbin/adduser: line 95: ` usernameftp=${username}ftp'

You're doing a case. The error is saying it didn't expect a newline because it thought you were still doing the first case test.

Remove the ";;" from below the y|Y) line and add it to the end of the line just above n|N.

Also you should remove the ";;" below the n|N) line as the last line of the case before the esac is the end of the case so doesn't need continuation like earlier steps.

Also it is good practice to have *) condition as last one of a case to make it give an error message if any input other than that expected is given. i.e. What happens if the user types W instead of Y or N? If you did add such an option to your case you WOULD still want the ";;" after the n|N line but not after the new *) line.

Should be:

how do I write it to accept only y or n or Y or N?

The quotes around the variable aren't required and in some cases can cause confusion. Any way on second look I realized OP's issue is in the case above line 95 rather than line 95 itself. Often error output pukes on unexpected lines rather than the lines that are causing the problem before them.
