Need help running a SQL script in Toad

I need to make this work in Toad for Oracle while I get my SQLPlus working again.

This is the script that I am trying to run in Toad and is giving me a a little window with a field to enter the values I need but is not working:

REM
REM      File:      SFMAILGxxxxxxxxxxxxxxx_INIT.SQL
REM
REM      Description:      SQL*Flow Mail Gateway for PL/SQL Initialization
REM
REM    
REM
set echo off
set verify off
 
set define off
set define &

end;

***************************************************************************
This part of the script:  SMTPServerName                        =>      '&smtp_server_name',

'&smtp_server_name', this needs to be  whatever the server name is....

The parameters that need to go in there are:

Enter the following parameter values:
Application Function ID            : <Value from Query 1 above>        [261]
Action ID                        : <Value from Query 2 above>      [101]
SQL*Flow User                  : SQLFLOW_MAILxxxx
SMTP Server                  : whatever.whatever
SMTP Port (Default=25)            : <ENTER>
UTC Offset Hours (Default=-5)            : <ENTER>
Use File Logging (TRUE | [FALSE])      : TRUE
Log Normal Messages (TRUE | [FALSE])      : TRUE
Log Directory  (on DB/CM Tier)            : /site025/app/common/sitetmp <--whatever example
Log Filename (e.g. 'sfmailgw.log')            : xxmailgw.log
Polling Interval ([60] seconds)            : <ENTER>

That is how it used to work so well in SQLPlus all I had to do was enter the values.

  I am sure this is not very clear so ask me for what ever is missing for you to understand me better :).

Thank you!
