trying to add options in powerstore 4.5

I am trying to add options to a product in powerstore. My wife teaches cake decorating classes and I need to have different days of the week as one option which I can do. The problem arises when I need to add some supplies for the class as a second option if the students don't have what they need. These options don't affect the number of students, which in this case is the inventory, in the class only the price.

please provide more details.

What is the problem you are having trying to add these options?

Please provide a step by step guide to the process you are using to add the options, and a description of the problem you are encountering versus what you are expecting to happen.

I am trying to add options to the classes that are being taught on Thursday and Saturday. It is the same class being taught on both days and I figured out how to add the day of the week as an option. For some of the classes the students can buy the supplies they need for that class. I would like to be able to add the option to the class day but adding the supplies does not increase the inventory of the classes which are limited to 8 students. I cannot seem to figure out how to do this if it is even possible. I have put a link in the cart description to have the students be able to add the supplies from there but I would like to be able to do it from the options, if at all possible.

For this, you would need to make each class day a separate product, rather then making the days an options

create a product for:

class1 - Monday

and another product for class 1 - Tuesday / Thursday

you can then add the supplies as simple options to class - day product.
