Hi Maurice

mabe this helps:

function brCount(objForm)
{
 var arrNewlines = objForm.area1.value.match(/\n/g)
 alert(arrNewlines.length);
}

<form onSubmit="return brCount(this)">
<textarea name="area1"></textarea>
<input type="submit">
</form>


When posting this form it will alert you the number of newlines found in the
textarea.
You can test the arrNewlines.lenght to see the number of newlines in the
field.

kind regards,
johannes
