One field validates the other

Morning,

I can't get the syntax just right. What I need it to do is say if one field is NOT NULL/Blank then make sure the other field is filled in.

This is what I have:
<script language="javascript">
if (!(formname.InternetAccess.value == "" && formname.VPEmail.value == ""))
{
alert("Please enter your VP's email address.");
return false;

}

return (true);
}
</script>

Any thoughts would be greatly appreciated

Thanks

Laura

try this

if ((formname.InternetAccess.value != "") && (formname.VPEmail.value == ""))

Hmmmm.

Still doesn't check. This is the whole thing:

<script language="javascript">
function Form_Validator(testform)
{
if ((testform.InternetAccess.value != "") && (testform.VPEmail.value == ""))
{
alert("Please enter your VP's email address.");
return false;
}

return (true);
}
</script>

<form name="testform" method="post" onSubmit="return Form_Validator(this)">

I just tested it and it worked fine. what does the rest of your form look like. I made my own to match because you did not include the code for yours.

This is the form part:

<form name="testform" method="post" onSubmit="return Form_Validator(this)">
<p><font face="Arial, Helvetica, sans-serif">VP email address:
<input name="VPEmail" type="text">
</font></p>
<p><font face="Arial, Helvetica, sans-serif">Internet Access:
<select name="InternetAccess" size="1">
<option selected> </option>
<option>Internet Access</option>
<option>Internet Access Enhanced</option>
<option>Intellitrader</option>
</select>
<input type="submit" name="Submit" value="Submit">
</font>
</form></p>

The problem is that your select box options do not have any values set. So either you need to add values to the options...

<option value="IA">Internet Access</option>

or if you dont want to do that, you can use the selectedIndex property of the select box to determine if a selection has been made...

if ((testform.InternetAccess.selectedIndex != 0) && (testform.VPEmail.value == ""))

Your brilliant Thanks so much...
