Did you try longest or cross-product Lacing? 
Shortest lacing.
Are you trying to set the parameter values? If so you are nearly there anyway, for the pictured workflow all you need is to use a String.ToNumber node after your String.Replace node.
There are other ways of mapping these values to match the list structure. Just not at the PC right now. Community chime in here 
and I’ll post some more options later anyway.
Do you want to remove duplicated items?
