search\_form.search\_author.value=""

In IE7 it works find, but in FF3 I get the error search\_form is  
undefined. search\_form is the name of my form.

Thanks for the help!

Easiest thing is to include “id” parameter to your form and use  
prototype matcher $(‘myformid’) - it’s probably most cross-browser  
behavior.

I believe document.forms[‘search\_form’]… should also work across  
browsers (without requiring prototype)
