Not calculating unless all (optional/ hidden attributes) are selected.

Krzysztof, first of all thank You for Your wonderfull, customizable and probably the most robust calculation plugin!

I watched the videos, but there’s no mention on this. I have some optional attributes (like LED color) which are hidden if the visitor select a parent option of NO LED. The calculator however will not compute the price – I have debug output set to ON – and says I need to select all attributes. The LED Color attribute is hidden though thanks to the show/hide logic. What am I doing wrong? Thank You!
