IfError

How to Use the Power Fx IfError Function in Power Apps

Using the IfError function in Power Apps can save you time and effort by preventing errors from occurring and ensuring that your data is accurate. In this article, we will discuss how to use the IfError function in Power Apps.

Syntax

The basic syntax for the IfError function is as follows:


IfError(Value, Value if Error)


The IfError function takes two arguments: the first argument is the value to be evaluated, and the second argument is the value to be returned if an error is detected. If no error is detected, the function returns the original value.

Examples

Let’s take a look at some examples of how to use the IfError function in Power Apps.

Example 1

Suppose we have a table named “Sales” that contains information about our company’s sales data. We want to calculate the total revenue for each month. We can use the following formula:


Sum(Sales, Revenue)


However, if there are any errors in the “Revenue” column, the formula will return an error. To prevent this from happening, we can use the IfError function:


IfError(Sum(Sales, Revenue), 0)


In this example, if there are any errors in the “Revenue” column, the IfError function will return a value of 0 instead of an error.

Example 2

Suppose we have a form that requires users to input their age. We want to ensure that the input is a number and not text. We can use the following formula:


Value(TextInput1.Text)


However, if the user inputs text instead of a number, the formula will return an error. To prevent this from happening, we can use the IfError function:


IfError(Value(TextInput1.Text), 0)


In this example, if the user inputs text instead of a number, the IfError function will return a value of 0 instead of an error.

Example 3

Suppose we have a table named “Employee” that contains information about our company’s employees. We want to calculate the average salary for all employees. We can use the following formula:


Average(Employee, Salary)


However, if there are no values in the “Salary” column, the formula will return an error. To prevent this from happening, we can use the IfError function:


IfError(Average(Employee, Salary), 0)


In this example, if there are no values in the “Salary” column, the IfError function will return a value of 0 instead of an error.

In conclusion, the IfError function is a useful tool that can save you time and effort by preventing errors from occurring in your Power Apps formulas. By using the IfError function, you can ensure that your data is accurate and your formulas are working correctly. So, next time you’re creating a formula in Power Apps, consider using the IfError function to make your life easier.
