Describe the problem/error/question

If am building a workflow to create and store a proposal (google docs ) in a client folder.
I need to check if the client folder exists and create if it doesn’t. Then save the proposal in the folder.
My ideal was to create a folderId variable to empty with set (edit field) node. Look for the client folder (google drive node) based on its name. depending on the result, create the folder and store its id in the folderId variable.

How do I create a local variable ? If set (edit field) node is the correct way, how to I get the variable on a downstream node ?

What is the error message (if any)?

You can use either Set or Code nodes. To refer to the property (aka variable) downstream if not directly attached, you would need to utilize the node reference as in Output of other nodes | n8n Docs.
