different size and price options in ps 4.5

I am having trouble setting up options for individual products in PowerStore 4.5. Can you please provide a simple step by step procedure

I have a wine barrel product with 4 different sizes and each size has a different price

How can I configure this on the individual product page?

Thank you.

In the admin section, go to Products -> Add New Product

Fill in the product details for the main product, then save it.

once the product is created, go to the product update page for that product and click the button to add Options.

Since the options will effect price, select Advanced options.

Set the name of the option to Size, when prompted, add the default size.

Add additional options for the product to the list, then click finish to go back tho the product update page.


from the "Choose the variation of this product to edit..." List chose each option, make sure the "Only update <option name> options" box is checked, update the price and click the update button.

I can add the sizes and prices. It is when I click to order an item, if I order a different size, the cart shows the wrong price. It shows the default price. How do I get it to sync the correct price with the correct size?

It looks like you created a new option group for each size, instead of adding the sizes to the size option group. See the attached screen shots for more details.
