Function is showing up with errors on the page (newbie)

[je150]

I wrote a function to make sure that all fields are set before the information is submitted. Unfortunately the submit button does nothing and ie says there are errors on the page.

<script language=javascript>
function checkform()
	{
	if (document.createuser.Name.value=="")
		{
		alert ("Name Field is Blank");
		}
	else
	{
	if (document.createuser.Email.value=="")
		{
		alert ("Email Field is Blank");
		}
	}
	else
	{
	if (document.createuser.Password.value=="")
		{
		alert ("Password is Required to Create a User");
		}
	}
	else
	{
	document.createuser.action="create_check.php";
	document.createuser.method="post";
	document.createuser.submit();
	}
	}
</script>

and the form

<form name="createuser">
		<TD>Full Name:</TD>
		<td><input type="text" name="Name" size="24" maxlength="24"></TD>
	</tr>
	<tr>	
		<td>Email:</td>
		<td><input type="text" name="Email" size="24" maxlength="24">@email.com</td>
	</tr>
	<tr>
		<td>Password:</td>
		<td><input type="password" name="Password" size="8" maxlength="8"></td>
	</tr>
	<tr>
		<td></tr><td><input type="checkbox" name="admin_check">Admin Rights?</td>
	</tr>
	<tr>
		<td colspan="2" align="center"><input type="button" class="submit" value="Create" onclick="javascript:checkform();">
	</tr>
</form>

Im thinking i just did something stupid. Any help would be appreciated, im completely new to writing javascript..

Nevermind I fixed it!
After coding php for weeks, i figured out that you cant immediately close else statements in javascript

<script language=javascript>
function checkform()
{
    if (document.createuser.Name.value=="")
        {
        alert ("Name Field is Blank");
        }
    else
    {
    if (document.createuser.Email.value=="")
        {
        alert ("Email Field is Blank");
        }
    else
    {
    if (document.createuser.Password.value=="")
        {
        alert ("Password is Required to Create a User");
        }
    else
    {
    document.createuser.action="create_check.php";
    document.createuser.method="post";
    document.createuser.submit();
    [COLOR=red]}}}[/color]
}
</script>
