[garfield11]

Hi all,

Below are 2 radio button to display either Contact type is by phone call or thru' meeting:

<TR><TD valign=&quot;top&quot;>Contact Type ?</TD>
<TD valign=&quot;top&quot;><INPUT TYPE=&quot;radio&quot; name=&quot;ContactType&quot; value=0
<% ' Check this radio button if the existing value = 1
If edit <> -1 Then
If objRS(&quot;ContactType&quot = False Then
Response.Write &quot; CHECKED &quot;
End If
End If %> checked>Phone Call</OPTION>    

<INPUT TYPE=&quot;radio&quot; name=ContactType value=1
<% If edit <> -1 Then
If objRS(&quot;ContactType&quot = True Then
Response.Write &quot; CHECKED &quot;
End If
End If %>>Meeting</OPTION></SELECT></TD></TR>

Now, how can i make a javascript to check
- if user select &quot;Phone Call&quot; option they must fill up the phone number in the text box else an alert message will pops out?

Thanks!

function checkContact(f) {

if (f.ContactType[0].checked && f.phoneNumber.value==&quot;&quot
{
alert('You must fill in the phone number');
return false;
}

else
return true;
}

phoneNumber - is the name of text field.

Don't forget about <form> and </form> tags!
The call of checkContact() function should be like this:
<form ... onsubmit=&quot;return checkContact(this)&quot;>

Yes, it's a shortcut to document.forms[0]. I pass the form object as a parameter here:
&quot;return checkContact(this)&quot;, therefore you don't need to write an actual form name.
