Decrement Variable

Decrement Variable node is designed to decrease the value of a specified variable by a given amount. This node is useful for countdowns, reverse iterative processes, or any scenario where you need to systematically decrease a numeric value in your workflow.
Specify the name of the variable you want to decrement.
Enter the decrement value (the amount by which the variable will be decreased).
The node will retrieve the current value of the specified variable.
It will then subtract the provided decrement value from this variable.
The result of the subtraction will be stored back in the same variable, overwriting its previous value.
If the variable doesn't exist, it'll raise an error.
The node updates the value of the specified variable with the result of the decrement operation. You can access this updated value using Magical Autocomplete (e.g.,$.variables.<variable_name>
) in any node below this node.
Let's say you want to decrement a countdown timer by 1. You already have a variable countdown
:
Set Variable name to $.variables.countdown
Set Value to 1
If countdown
initially had a value of 10, it will now be 9.
Ensure that the variable you're decrementing contains a numeric value to avoid type conversion errors.
Always ensure that the variable is initialised before using this node.
