Workspace Transfer Error while exporting geometry from PDE toolbox using Export Geometry Description, Set Formula, Labels from the Draw menu

Trying to export geometry description function from PDE App, I am getting Workspace Transfer Error with the following text: You did not enter enough variable names. Please, try again.

Could someone explain how many variable names I have to enter, please?

Thanks in advance
