struts html:form with javascript for ajax

Hi

I have a struts (1.1) form

<html:form

<html:text
<html:text ...

</html:form>

All was well until I wanted to add an ajax field that would do auto-
complete.
Previously working example had
<input id="complete-field"

This was incompatible with the html:form tag and so I continued to use
<input

but when I submit the form the value of the input field is null

How can I modify my form so that I can use the javascript
functionality ?

Thanks

.
