Mike Jolley on "[Plugin: WooCommerce] Product variations will not custom"

I already make attributes and set in to variation.
The attributes are nett weight and price.
It supposed when customer choose nett weight 200gr the price should set automatically to Rp 50.000.
The problem is, the price won't change automatically. There are 3 options nett weight with 3 different prices. I've change the attributes to custom ordering and name but there aren't changes.
please help me.
