how to add onclick

i have a jpg, and on the top of the jpg i have a little picture, how to ad the condition "on mouse click object" and that do another action???

i have added a button, invisible, but when i add the condition on click, that dont work, i cant go to the next frame.

Why when a button is invisible, if i add onclick that dont work???

Mouse "on object click" button

->do whatever

If its invisible i don't think it will register that its a button though.

Try not making it invisible, but simply an empty blank sprite instead if you need it to start visually invisible but still clickable

but where is the condition mouse??
