Hi code-ninja!

When you pass through the list you check if the current element is the one you want to remove:

if($temp->[VAL] == $ele) {
and if it isn't, you move to the next element:
$temp = $temp->[NEXT];
However the pred-Element still stays the first one ... so when you remove the 16, you would link the 25 directly after the 1. You will need to adjust pred also.

note: your code also needs some adjustment if you want the possibility to delete the first element.

HTH, Rata

    perfect. That was a stupid mistake. :/
    ... } else { $temp = $temp->[NEXT]; $pred = $pred->[NEXT]; # this is what you are saying. } ...
