Text overflows column 1 of a two column CSS layout

[jimchapuk]

I created a two column CSS layout by
floating the columns left and right respectively.

When I put text into the first column (via HTML) it continues in
a straight line through the second column and beyond
instead of going onto a new line within the first
column when it reaches the right hand edge of the
first column.

The code is below. Main is the name of the left hand
column and ads is the name of the right hand column.

If you've got the time, have you any idea what is
wrong.

Please do not post in the Articles section.
Also, please use code tags.

I don't see the problem. We need to see the html, too.
