Raymond,
What sort of error are you getting?
One of the most useful tools in your toolbox is the print() function.
Try doing something like this:
$sSQL = "SELECT '$car' FROM varetabell WHERE carid='$carid'";
print ($sSQL);
$sql = mysql_query($sSQL);
$myrow = mysql_fetch_array($sql);
$x = $myrow["$car"];
This will let you see exactly what query is being passed to the
database, and that alone will frequently tell you where the problem
lies. That is probably the best place to start.
FWIW, in almost all of my database interactions, I set the query as a
separate string variable, just so that I can use this sort of debugging
technique.
