Key Schedule not working

Key Schedule node doesn’t add a parameter at all and I can’t even work out why it not behaving normally.

As what you see in my image, I have made the list for parameter name and it doesn’t added into the key schedule.

I have read the description in but I have no knowledge for Python script so I don’t know what I am doing wrong as I thought it should be straight forward by adding the parameters name from the list to the key schedule.

Could anyone help me with this?
