Easily :
You are not saying which browser you have been using.
You have not posted complete working/failing code.
You have not reported the output (including "none") of the browser's
native, or another, debugger.
You've not remembered things said in the newsgroup FAQ.
You've not said exactly what you expect, nor what you get - that code
works as it should, only your expectations were wrong.
And, as a minor detail, your code is wrong.
To convert a typed input String to a Number, unary + is commonly best;
neither too liberal nor too rigorous. For example, AInput = +field .
Then check that the value of AInput is admissible.
And, posting from -0400, should you
be spelling Millimetres correctly ?
