Feat selection is a little bugged.
First not every feat has description and its better to show summary instead.
Second qualified show is wrong.
Formulas should be (first feat example):
=WENN(ISTLEER(BF82);"";SVERWEIS(BF82;Table_Feats;6;1))
=WENN(ISTLEER(BF82);"";SVERWEIS(BF82;Table_Feats;7;0))
Sorry, german Excel version but it should be clear what i mean.
But with changing this another "little" bug comes out.
If you select a feat that depends on another feat a circle error occurs if you choose this feat as first feat.
