00:00:08

In this guide,

00:00:09

we'll explore five essential logical functions

00:00:12

if

00:00:13

and

00:00:13

or

00:00:14

not and switch.

00:00:16

First,

00:00:17

the if function is similar to the if

00:00:19

statement in Excel and other programming languages.

00:00:23

It allows you to test a condition

00:00:25

and execute different actions based on the result of that condition.

00:00:29

For example,

00:00:30

if you want to display a personalized welcome message based on the user's role,

00:00:35

you can use the if function as follows.

00:00:38

Here,

00:00:38

if the user types manager in the text box,

00:00:41

the message displayed will be

00:00:43

welcome

00:00:44

project manager.

00:00:45

Otherwise,

00:00:46

the message displayed will be welcome collaborator.

00:00:50

Next,

00:00:50

the and function is used to check if multiple conditions are all true.

00:00:55

This is particularly useful

00:00:56

when you want to ensure that several criteria are met before proceeding.

00:01:01

For example,

00:01:01

in a customer feedback form,

00:01:03

you want to ensure that the name and

00:01:05

email fields are filled before submitting the form.

00:01:09

Here's how to do it.

00:01:11

If both fields are completed,

00:01:13

meaning neither text input is left empty,

00:01:15

the message displayed will read,

00:01:17

thank you for your feedback.

00:01:19

Conversely,

00:01:20

if any field is incomplete,

00:01:21

the message displayed will be,

00:01:23

please fill in all fields.

00:01:26

The or function allows you to check if at least one of the conditions is true.

00:01:31

It is handy for scenarios where a single

00:01:33

true condition is sufficient to trigger an action.

00:01:36

For example,

00:01:37

if you want to check if an employee is either on leave or working remotely,

00:01:40

you can use the your function as follows.

00:01:43

If the employee's status is leave or remote work,

00:01:47

the message displayed will be the employee is not in the office.

00:01:51

Otherwise,

00:01:52

the message displayed will be

00:01:54

the employee is in the office.

00:01:57

The knot function inverts the result of a condition.

00:02:00

It is useful when you want to check that something is not true.

00:02:04

For example,

00:02:05

in a security application,

00:02:06

you want to ensure that the password field is not left empty.

00:02:10

Here's how to do it.

00:02:12

If the password field is not empty,

00:02:14

the message displayed will be password validated.

00:02:17

Otherwise,

00:02:18

the message displayed will be please enter a password.

00:02:22

Finally,

00:02:23

the switch function is used to compare an expression to multiple

00:02:26

values and execute the code corresponding to the first match found.

00:02:29

For example,

00:02:30

in a customer service application,

00:02:32

you can display a specific message based on the nature of the user's request.

00:02:37

If the user types technical support,

00:02:40

the message displayed will be,

00:02:42

we will connect you with technical support.

00:02:45

If the user types inquiries,

00:02:47

the message displayed will be,

00:02:49

our inquiry team will contact you shortly.

00:02:52

For any other input,

00:02:53

the message displayed will be,

00:02:55

please specify your request.

00:02:58

In summary,

00:02:58

logical functions and power effects make

00:03:00

Power App's applications more dynamic and interactive

00:03:04

by intelligently responding to user actions.

00:03:06

We've seen how to use the if,

00:03:08

and,

00:03:09

or not and switch functions through practical examples.
