Create a simple counting PowerApp

[paulb4]

Hello,

First of, sorry I really don't know anything about PowerApp so please be comprehensive...

I'd like to create a simple app which can be used to count people in a building.

I need that several people can use it simultaneously:

- You enter a number (let's say you type 50 (=people already in the building before counting starts))

- The person at the front door can Add 1 by pressing a button for every person who enters

- On the other side of the building another person can Substract 1 by pressing another button

That way I can have the real number of people in real time.

Can someone explain how to do that, please? What functions to type? And so on...

The best would be that the counting evolution would be saved somewhere (like a reporting) but I don't know how to do it...

It might look like this:

See? Nothing fancy really...

 Thank you in advance!!

Put this code in the OnChange property of the Text Input

Set(peopleCount, Value(TextInput1.Text))

Make sure to set the Format  property of the Text Input to this code

Number

Use this code in the OnSelect property of the +1 button

Set(peopleCount, peopleCount + 1)

Next, this code goes in the OnSelect property of the -1 button

Set(peopleCount, If(peopleCount > 0, peopleCount - 1))

To display the current number of people in the building put this code in the Text property of your label or text input.

peopleCount

Hello @mdevaney 

Sorry I don't know what you mean by the last step:

To display the current number of people in the building put this code in the Text property of your label or text input.

peopleCount

I don't understand where I am supposed to type "peopleCount"... Can you be more specific, please? Where is the Text property field?

Thank you!

Yes, use the variable peopleCount in the Default property of the Text Input or the Text property of a label.
