How to use a variable to replace a static value within formatDateTime function?

Question

I am trying to make my ADF expression more dynamically by replacing some static value with a variable within formatDateTime function.

I am trying to use a variable to change this value 2 as this value can be changed to 2, 1 or 0.

How do I express in the variable?

I tried with something like this, but I am getting an error like below:

Answer 1

As the error mentions that your parameter should be an integer and not Text as you are defining it :

Based on the documentation :

Data types can be String, Bool, or Array. Optionally, you can also assign a default value to the variable. This value will be used as the initial value of the variable at the start of a pipeline run

You need to convert it in the expression using int() function.
