Thank you for your reply.
I've just tried what you said, I not 100% sure if I did it right, here's what I done:
1st I moved the 'On any touch end" out of the sub event making it not a sub event but it is still in the group, that didn't work.
2nd I highlighted the 'On any touch end" and pressed CTRL + x which deleted only the wording, the events stayed there, I highlighted the 'group' (where the group name is) but it wouldn't allow me to press CTRL + v, so I highlighted just under the group (so the whole of the group lit up except the group name) I then CTRL + v, that pasted 'On any touch end" right about the touch green button part.
This kinda worked and stopped me from firing the bomb while the first one was still active in the game.
But it stopped the power bar going up which didn't allow the bomb to go at the speed that it would have for holding down the button for a time.
Sorry if I've misunderstood what you've wrote.
