Yes it has to both work and validate. I've taken the <h1> out, the <font face> and the <table border="0" width="100%"> and it validates and still works, but obviously there is no heading. I can set the font to Verdana individually. I will play around with it again tonight, I won't rest until it works.
Tangor...thanks for that, I noticed that after a previous poster mentioned it and have fixed it. In the learning guide we were given it told us to use <br/> for line breaks, but when I went to validate the webpage every one came up with a warning so I thought I had altered them all.
