Check if player has enough balance with SkBee scoreboard

Skript scoreboard balance check
Suggested name:

Spigot/Skript Version:
Skript 2.6.3
What I want:
A skript that will check if the player has at least 50 on {balance::%player's uuid%}
I have a basic SkBee scoreboard, and when a player clicks, they get 1 balance.
{balance::%player's uuid%} is how much balance they have, and I want the code to check if they have
50 balance on {balance::%player's uuid%} BEFORE it takes away the 50, otherwise if the player doesnt have at least 50 on {balance::%player's uuid%}, I want it to cancel the event
Heres my code so far, without the balance check

on right click with oak button:

add -50 to {balance::%player's uuid%}
remove Sunflower from player's inventory
give player Red Mushroom named "&4Red Mushroom Clicker"

I don't want the player to go into the negatives, so I want the code to make sure they have 50 balance on {balance::%player's uuid%} before it actually takes it away, otherwise cancel the event.
