Hi, I'm new to Shopify...and trying to create my eshop. I sell wool and each ball of yarn has a different color. In product I've added a variant for color and the related imaged for each color. When I check product page preview, if I click the color reference I can get the image related to that reference, but if click on the image I cannot get the reference changed. That's is a real problem because if a customer choose a color just by clicking on the image, and then click add to the basket, most likely the reference will not be correct.. Does anyone know how to fix it ??? Thanks !
