How to make a field "REQUIRED"

[bkoltys]

Trying to make certain fields "Required" on my "get info" screen in my web page. Example, someone fills out their name, address, city, etc but forgets to put in a ZIP CODE I need a window to pop up that says "Zip is a Required field" or somehting to that effect. This is what I have now.

<TD WIDTH=&quot;37%&quot; VALIGN=&quot;MIDDLE&quot;><INPUT TYPE=&quot;text&quot; NAME=&quot;21zip&quot;></TD>
</TR>
<script language=&quot;JavaScript&quot;>
var response = &quot;21zip&quot;
if(response == &quot; &quot
{alert(&quot;Entry Required&quot
}
</script>


Any ideas??

<script>
function validate(){
if (document.formname.21zip.value=&quot;&quot {
alert (&quot;you have to fill all the fields i said !&quot
return false
}
return true
}
</script>

and
<form name=formname>
INPUT TYPE=&quot;text&quot; NAME=&quot;21zip&quot;>
</form>

if (document.formname.21zip.value=&quot;&quot {

should be:

if (document.formname.21zip.value==&quot;&quot {

yes, and i also forgot this very important call :
<form name=formname onsubmit=&quot;return validate()&quot;>

thank you jared )

time to go back home, too much work today turned my brain into a ... black hole ....

you might want to do it like this so you wont accept a whole bunch of spaces:

if (/^\s*$/.test(document.formname.21zip.value)) { jared@eae.net -
