Save Button Problem in IE7

Hi,
I am unable to submit a form in IE7 using form_remote_tag , this works
pretty good in FF and Safari too.
View :
   1. <body>
   2. <%= form_remote_tag(:url => {:controller => :account, :action =>
:update_profile},
   3. :before => "if (!validateProfileFormOnSubmit(this)) {
return false; }") %>
   4. <div class="profile_section">
   5. <div class="section_header"><%= image_tag
"user_profile/title_general.gif", :alt=>'General Info', :size => '95x12'
%></div>
   6. <div class="left_column">
   7. <form>
   8. <fieldset>
   9. <ul>
  10. <li class="language">
  11. <label>Language</label>
  12. <input name="gen_info[language]" value="1"
checked="checked" type="radio"><label for="language_english">
English</label>
  13. <input name="gen_info[language]" value="2"
type="radio"><label for="language_french"> French</label>
  14. </li>
  15. <li><label class="medium_width" for="email">Email
Address</label> <input size="25" id="email" name="email" value="<%=
@current_user.login %>" readonly="readonly" type="text"></li>
  16. <li><label class="medium_width"
for="full_name">First Name</label> <input id="first_name"
name="gen_info[first_name]" value="<%=
@gen_info.first_name.strip.squeeze(" ") %>" type="text"></li>
  17. <li><label class="medium_width"
for="last_name">Last Name</label> <input id="last_name"
name="gen_info[last_name]" value="<%=
@gen_info.last_name.strip.squeeze(" ") %>" type="text"></li>
  18. </ul>
  19. </fieldset>
  20. </div>
  21. <div class="clear"></div>
  22. </div>
  23. <div id="save_profile"><%= image_submit_tag
"buttons/save_profile.gif" %></div>
  24. </form>
  25. </body>
  26.
  27. CSS:
  28.
  29. div#user_profile_container div#save_profile {
  30. text-align: center;
  31. width: 785px;
  32. margin-left: 36px;
  33. padding: 15px 0 0 0;
  34. }
  35.
  36. div#user_profile_container div#save_profile input.save_profile
{
  37. margin: 10px 0 10px 0;
  38. }

i was unable to understand why this is not submitting in IE7 and when
clicking on submit button the console is not generating any output and
the image path i had given is correct though;

any HElP ??
