Hot Cars- site looks different on I.E. and Firefox

I have done all of my editing to the site in firefox. I want the headlines in the street, on the site to be underlined. They are underlined in firefox, but not in I.E. 7. I tried editing the text to make it underlined in I.E. 7, but it does not allow me to change it. When viewing the site in I.E. 9 the headlines in the street ARE underlined. Can you please help me figure out how to get the headlines underlined to show in I.E. 7? I tried changing my browser settings and deleting my cookies, none of that worked. Also, I have a contact form on the site. I want to make the contact form text white. However, I cannot seem to find where to change this. I was able to make the text white under the contact us slider tab, but not under the contact form slider tab. Your help is greatly appreciated. Here is a link to the site: online.citycountycu.org/index.php?option...tact&id=1&Itemid=123

Add this to bottom of template_css.css:

.newsflash p a span
{
text-decoration: underline;
}

for contact form add this after that:

#contact-form label
{
color:#FFFFFF;
}

Thank you! That worked perfectly for the underlining! The contact form text all became white, except for the words: "Send an email. All fields with an * are required." How can I also make that text white. Thanks soo much!!

Add

#contact-form legend
{
color:#FFFFFF;
}

Thank you so much! That worked perfectly!
