Need help for AutoType script.

Hello there,

I need some help.

I found an AutoType script,but I need to set it to work like I want to.
So,the script work like this,when you set it up,you run it,and then the script will start typing your word after 5 seconds.
But,I want to make the script typing my word after the chosen message,like if my friend type "Go on" message,I want script to start working right after his message.
Here is the script,please,if someone can fix it and make it work like the way I said here,I would be so thankful!!!

set shell = createobject("wscript.shell")
strtext = inputbox("What would you like the message to be")
strtimes = inputbox ("How many times would you like you type it?")
if not isnumeric(strtimes) then
lol=msgbox("Please write a NUMBER nextime")
wscript.quit end if msgbox "After you click ok the message will start in 5 seconds " wscript.sleep(5000)
for i=1 to strtimes shell.sendkeys(strtext & "")
Shell.SendKeys "{Enter}"
wscript.sleep(75)
next
