How do I stop a piece of code?

Okay, I have this code : When XP is greater or equal to 100, change level up by 1 and show text "LEVEL UP!", wait 3 seconds, fade "LEVEL UP!". Once I reach past 100, it starts constantly level upping because it runs the action more than once..

how could I stop this?

You could make like this:

after you put it to fade put an other action XP set value to 0 ( like reset it )

Radulepy But the player needs to KEEP the level, on the top it shows text saying level : (level #)

and other code I'm soon going to make will rely on that, such as if I want his weapon/clothes to upgrade once the player reaches, lets say, level 4, or a boss fight will occur on level 10.

Add a system trigger once condition..?

Thanks, I always looked for something like that by right-clicking,
