List Question

Hello, I have a quick question regarding lists, (Please see image below) I want to grab item number 6 from my list which is my drawing sheet number and arrange them in numerical order but the string.tonumber node is giving me an error: Warning: String.ToNumber operation failed.
Not a valid number.
Parameter name: str

Can anybody explain to me what I am doing wrong please ?

You’re pulling sublist 6 not item 6 of every sublist. Look into list @ level functionality.

or you might want to try using “Transpose” as this will group all the sublist values at 6 together then “Get item at index” to retrieve that list :grinning:
