How to update a single value?

[JosePerez]

Hi

I've been messing arround with PowerApps, and I just don't get how it works. This is what I'm current;y trying to do.

I have a list of people. Each people has a few values, like Name, email, etc. And there is a value called NumberOfStrikes, which is a number.

In the details view of the person, I placed a button with the "+" sign next to the NumberOfStrikes vlaue. I want NumberOfStrikes to increase by one every time I press the button (and ideally, to save the update right away to the Data Source). So far I can't beguin to figure out how to do this.

I can't even change the text of the button when I press it. I tried using a formula on the OnSelect:

ButtonAdd.Text = "New Text"

I tried:

UpdateContext({Text:"New Text"})

But nothing I do has any result.

Any help would be apreciated.

Hi @JosePerez,

If here you are working with the Detail screen, then the formula under the OnSelect property of the '+' Sign should be:

UpdateContext({Input:Value(BrowseGallery1.Selected.NumberOfStrikes)+1});Patch(PeopleList,BrowseGallery1.Selected,{NumberOfStrikes:Value(Input)})

See if it would work in your scenario,

and if you have any further questions, please post back.
