You need some javascript to do this. In your header include the following: 
<script language='text/javascript'>

var oText=document.getElementById('MyTextField');

function toggle_display(n) 
{
   if (n=='show') {
      oText.style.visibility='visible';
   } else
   if (n=='hide') {
      oText.style.visibility='hidden';
   }
}

</script>

And in your CGI.pm generated text fields, include properties 
for the controlling field: 
     onchange=>'toggle_display(this.value)'
for MyTextField:    
     id=>'MyTextField'

It's really more of a javascript/css problem, but it can be solved within the CGI.pm framework.
