TD wave button system

Hello,I'm new to contruct and don't have much experience with making games,so I'll try explain as best as I can,I'm trying to make a simple tower defence game as a starting project,but as you can imagine having no experience I'm having some trouble.

So I created a wave system with a wave button,when the wave button is pressed the enemy spawns 1 enemy for wave 1,pressed again it spawns 2 enemies for wave 2 and so on,the trouble I'm having is the enemy keep spawing after the first button press,I followed a tutorial on this but I'm getting different results,any help would be much appreciated,or maybe I'm going about the wave system all wrong,if you have a better idea please share on how to do it.

You posted in the wrong forum, should be in the 'How do I' forum.

Anyway.. you need a condition for each wave. For example, something simple as this could work, though crude:

But it should be easy to understand.

Trigger once will make sure the whole event runs.. well, only once.

Moved to the C2 How Do I Section.

Thanks I'll try that
