Problemi:

Of a series of lists (0-1-2-3-4ecc.) eachone contains two informations about Name and Values.  
I must filters those lists that contain a certain name without loosing the value associate to It.

Example

List

> 0 list  
> Sun  
> 30

> 1 list  
> Sun  
> 45

> 2 list  
> Moon  
> 40

> 3 list  
> Star  
> 40

> 4 list  
> Sun  
> 50

From this lists I need to create a one list with only the lists containing the Word Sun an the related value

Anyone can help?

List.Contains into a List.FilterByBoolMask will work here. Watch your list levels and lacing closely, as the input for the ‘contains’ should be @L2 to ensure you catch everything.
