Call widget button variable from a different widget bp.

Hello everyone, i have two widget blueprints, A and B, Widget A has a “Set is Enabled” function for a certain button, if it hits certain requirements it will enable the button, everything functions ok here, the issue is i want to also impact the “Enabled” status of a button from Widget B, i tried copying the button variable from widget B into widget A but it doesn’t work. I have no idea how to use event dispatcher assuming that will come in handy. Please help, thank you!
