nowassist - VA - HOW we can get the variable from one topic to another (sub topic except those)

[jaiho_rai]

If we need to transfer from one TOPIC - variable values to another topic and assigned that value to there .

E.g if we have TOPIC A - take user input 

varInput.TopicAvariable = "Select value by user ";

Now in TOPIC B  I need to get that variable data and execute the TOPIC-B automatically:

varInput.TopicBvariable = varInput.TopicAvariable;

How can we achieve this ?

**Except these—subtopics I know**
