how do i use the cannon

[SWARTFDUPHIPH]

i have made the cannon on a tekkit server, i have cannonballs and gunpower and i have loaded the cannon but i am struggling to fire the cannon... help

[BloodravenD]

after you loaded a cannon up and used the gunpowder, use spacebar or whatever you use to jump to fire with it.

When I place my cannon its not there. But when u walk over it it glitches ur walking. And u cant load any gunpowder or cannons. Any ideas?
