Divs jumping

[ben03]

Hi,

Have recently been working on a new page. It still has plenty of work to be done to it but one particular problem arose that I can't seem to find a solution for. A number of DIVs added lower down the page are jumping out of the container DIV to the right for seemingly no reason: http://www.jab-ride.co.uk/trypageout

This is the CSS of the divs in question:

#aboutteam {
position: absolute;
top: 590px;
left: 25;
width: 830px;
z-index: 6;
}
#abouttext {
position: absolute;
top: 630px;
left: 725;
width: 140px;
z-index: 7;
}
#additional {
position: absolute;
top: 1350px;
left: 625;
width: 240px;
z-index: 6;
}
#contactinfo{
position: absolute;
top: 1350px;
left: 25;
width: 540px;
background-color: #dddddd;
z-index: 6;
}

If anyone can spot the error in the code I would really appreciate it!

Thanks
