horn problems

["bernd" <bernd.vabeach@erols.com>]

Hello :

took the MGB for a 200 mile run yesterday and at one point I had the urge to
use the horn, no sound!!, as I was driving I took the horn push button off the
steering wheel, looks to have a good connection.
What oh what could the problems be?????
as always TIA
