Browse for a list type in variable


i am trying to insert a new type of variable: type list (system.collection.generic list) and i encounter an error - see picture attached

i would use some help. thank you

You need to specify the type of objects that the list will contain (in the combobox between the “Type Name” filter and the list of types).
If you don’t know what you want to put in that list (or you need multiple types of objects), you can allways use Object (the result will be a System.Collections.Generic.List<System.Object>), but you will have to handle the type conversion before using the values from the list.
