How to set created widget to UI variable?

Here is my blueprint. As you can see, I successfully set a “create widget” object to a variable in the health widget, but for the other one (set up exactly the same way) it isn’t allowed? I’m a total beginner to Unreal so I’ll need to have any answers explained step by step than just be given a general answer like “just do this”.

The easiest way to save this return variable from your Create Damage … Widget node is to right click the Return Value pin and “Promote to variable” and use the generated “Set” node instead of your “Damage Widget” set node. Remember to replace any uses of “Damage Widget” elsewhere in your blueprint with the newly created variable.

As the answer below states, “right clicking” on any pin will automatically create a variable of the correct “type”. If you are really new to UE4 the following may be helpful to you. Especially the videos on references, casting and variables will help you get a better understanding of what is going on. Hope it helps
