I need to add two numbers together, unfortunately one of them is a

Keith,
You could chop characters off the front until you've got a numeric:
while (!is_numeric($sString) && $sString > "")
{
$sString = substr($sString, 1);
}
or you could delete all non-numeric characters wherever they appear:
$sString = preg_replace("/[^\d\.\-]/", "", $sString);
