Multiple forms

Hi! Greetings to all! I am new to rasa and the forum. I am working on forms and have multiple forms that I have to activate back to back. Now after 2 forms are done, I have to check the slot value and activate either the 3(a) or the 3(b) form. I was trying to add an action after second form submission to call on the next form based on the slot value but that isn’t working. Can anyone here suggest a way to deal with this situation?
