Conditional column

[Anonymous]

Hello all,
I have the following case:
If the number from the TopMaterial column corresponds to the number from the Material column. Should both rows from the TopMaterial in a new column be disregarded. The problem is that the material number only appears in one row. Thus, the column based on the unique number in column K should  be taken into account. Can anyone help me here?
