Hii everyone.

I need some help.  
The problem is I have a list with different values consisting out of interegers, strings and sometimes null values. This list wil allways be different in vallue and amount of list items  
the question is how do i clean up the list, so that i only get the items in the list that have a value?

here is an example

hey @James_Washbourne

Yes there is, but this does not remove the empty values from the list.
