If you want to communicate between two diagrams, then you shall declare the local variable as IAC ( Communication Variable) in both diagrams.
Source as out IAC and sink as in IAC. then values will be passed between two diagrams.

For converting an existing Local variable into a Global variable, move the Local variable from Variables tab to External Variables tab in the POU. Then copy this External Variable to Global Variables tab in the Application level.
