Simple variable creation

Simple variable creation

Can someone show me how to create 6 simple variables for Y (length 1, length 2 length 3, etc.) that can be created by an operator when starting the program?  I understand how to recall these during the program(I think), but not how to create the prompt for input. 

I've seen a couple questions about creating variables in CMM Manager, but I have to be honest, it all looks WAY more complicated than what I feel like I need.  I don't need to loop anything or create an outside data source.  https://support.qxcmm.com/portal/en/kb/articles/parametric-programming-part-families actually mentions EXACTLY what I want, but doesn't show how to do it:



I understand that the text file they go on to describe is more efficient, but I don't know VB script at all and I'd rather walk before I have to run.
I also have been pouring over the VB script guide, but I'm struggling to make heads or tails of it.  A very simple example of declaring a variable is what I need to see.
