javascript question

Im trying to get the value of a text box upon clicking a button

<form name="frm" method="post" action="default.aspx" id="frm">
<INPUT type="amount" value=1" onclick="this.value='';">
<INPUT type="button" value="Lookup" onclick="alert (document.frm.amount.value);">
</form>

any help? i keep getting not an object or null errors.

 

your TYPE for "AMOUNT" should be TEXT .. your name of that form element should be amount.

<form name="frm" method="post" action="default.aspx" id="frm">
<INPUT type="text" name="amount" value=1" onclick="this.value='';">
<INPUT type="button" value="Lookup" onclick="alert (document.frm.amount.value);">
</form>
