Hi,

I have this problem with sorting my data. I have data that is in two lists
like

col a---col b col d---col e
001 a 002 k
020 f 041 l
041 i 554 p

How can I sort all this data so that both column a and d would macth? And if
there is no match then it would leave the other columns empty

Like this

col a---col b col d---col e
001 a
002 k
020 f
041 i 041 l
554 p

I need your help very much!
