Decrease variable

Decrease variable is used to subtract a numerical value (defined in the Decrease by section) from a variable.

In the Output variable field, you can enter the same name as the old variable to subtract the value cumulatively, or enter a completely different variable name to save the result to a new variable without changing the old variable.

• Decrease by: The amount you want to subtract (e.g., 1, 2, 5, ...).

• Example: You have a variable $countdown = 10.

  • If you enter Output variable as $countdown and Decrease by as 1 ➡️ The variable $countdown will decrease to 9 (cumulative subtraction).

  • If you enter Output variable as $previousRow and Decrease by as 1 ➡️ The variable $countdown remains 10, while the new variable $previousRow will have a value of 9.
