Observe_field Firefox error

Rails
1

I’ve been having some problems in Firefox with observe_field.
Everything seems to work fine in IE, however when I try to observe a
select box nothing seems to happen in firefox. I downloaded FireBug to
investigate, and an error in prototype.js is raised

2751 getValue: function(element) {
2752 element = $(element);
2753 var method = element.tagName.toLowerCase();
2754 return Form.Element.Serializersmethod;
2755 },

Below is the error displayed in FireBug:

element has no properties
getValue(null)prototype.js (line 2753)
getValue()prototype.js (line 2875)
initialize(“paragraph[letter_type_id]”, 0.25, function())prototype.js
(line 2853)
create()prototype.js (line 37)

var method = element.tagName.toLowerCase();

I’ve read that this may have to do with how DOM is handled in IE vs
Firefox. Anyone have any suggestions?

It is saying that element is a null variable meaning that the string
element in line 2752 “$(element)” is not a valid id.
please post the rhtml template including the observe_field code and the
html element being observed

Your right. Thanks Keynan, I realized that I had only given the select
field a ‘name’ and not an ‘id’. I guess IE works with just a name, but
firefox must use the id to retrieve the element.

Thanks for your help.
