Droped Variables - How to undo after FLOW was saved.

I am new to the site as well as very new to WebMethods. I have a Flow service that I have dropped variables from the pipeline and now I would like to have them included in the pipeline. How can I “Un-drop” the variables?

I would think this would be a simple setting but I can not find any options.

I did not mean to post this here and actually found the answer to my own question. This post really should be deleted or moved but in case someone else wants to know the answer was to highlight the drop icon next to the variable name, right click and select Delete.

Just click on the cross Red mark in the pipeline tab when you highlight the dropped field you want it now and delete it.Also make sure it is the field you created explicitly.
