# Global and Local Variables Global and local variables in Sherpa Designer differ in their scope. The scope defines the context in which a variable is available for reading and writing: * Local — available only in the current diagram. * Global — available in all diagrams. In the lower central panel, a dropdown menu allows you to select the mode: * All variables are global — all variables will be available in all diagrams. * Global and local variables — for using both global and local variables in different diagrams.

If you need to manually switch the variable's scope, you must check the checkbox in the left column of the "Variables" panel.

When checked, the variable's scope becomes global. More about working with variables: {% embed url="" %}
