[SOLVED] Increment +10 -10 not working for pagination

[Guest elthomo]

Ok well my code on on the plus just sets the value to 10 rather than adding 10 to the value $startrow and the minus just sets the value to -10 rather than taking away 10 from the value start row. Any Ideas chaps??

 

echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.($startrow +10).'&zoek='.($zoek).'&searchcriteria='.($searchcriteria).'">Next</a>';
echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.($startrow -10).'&zoek='.($zoek).'&searchcriteria='.($searchcriteria).'">Previous</a>';

echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.($startrow +10).'&zoek='.($zoek).'&searchcriteria='.($searchcriteria).'">Next</a>';
if($startrow <10 )
{
echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow=0&zoek='.($zoek).'&searchcriteria='.($searchcriteria).'">Previous</a>';
}else
{

echo '<a href="'.$_SERVER['PHP_SELF'].'?startrow='.($startrow -10).'&zoek='.($zoek).'&searchcriteria='.($searchcriteria).'">Previous</a>';
}

Thanks for the quick reply but the problem is with the +10 -10 actually setting the value to 10 or -10 rather than adding or subtracting 10. So the webadress looks like http://www.myurl.com/search.php?startrow=-10 when the previous value was 10. (so it should have been 0) and clicking next always looks like  http://www.myurl.com/search.php?startrow= 10 not 20,30,40 and so on.
