Read above first, follow that. But also, if the two (or more) stools have different purposes, and you want to keep them separate objects then at least add them to a Stool "Family". This way you can combine them in Events and Actions.

So, Event 2 and 3 will be combined into one.
Also, Event 4 and 5 will be combined into one.
And, you don't need the Text to be updated every tick. You should remove that event, and update the text when the variable actually increments. So Set Text action can come after each "Add 5 to levelmoney" action. It will also improve performance as every tick text update takes a lot of CPU.
