I have a form with
within the body of your html document:
<form action="formHandler.php" name="yourForm" id="theForm" method="post"> <input type="text" name="fname" id="fname" /> <input type="submit" value="submit"/> </form>
You need to ensure you have the submit button within the form tags, and an appropriate action assigned. Such as sending to a php file.
For a more direct answer, provide the code you are working with.
