Importing products with multiple options

I am trying to import from csv products (windows) each of which has two Options (Glass and Glazing Bars)and each option has two variants.

I have succeeded in importing the products with a single option but if I then import an additional option it removes the first one. How do I include multiple options for a single product in a csv? I've read the documentation multiple times but while it gives an example of the end result it doesn't show how the csv should look.

I figured it out. The options need to be listed with a ";" between them and no space:)
