IE 6 and IE 5

Hi

I have coded a page at http://www.m-t-d.co.uk/friendsprovident.html
and it looks perfect in IE 5.

I sent it to my client and they say that they have got IE 6 and it is
showing bold all over the page and some questions are not
in bold. In short it does not look like what I am seeing!

They validated this because they have got some machines
with IE 5 and it looks perfect

I have not got a clue how to fix this.

Can anyone help me please?

Thanks

Sean
