I don't like the test if (n=>157) in your function, isn't if (n>=157) the right syntax?
And you can't change the text color just by ending msg.color = "red" (unless you have a script somewhere to handle it?)

But you can send msg.className and use CSS to change the colour.
Does this work?

jbudd you're a star. thankyou very much and yes I did spot my mistake in the if statement.( that what happens when you develop using different languages
