Hi There

I got a canvas app and a flow to send a confirmation per email.

The canvas app contains two gallerys where I relate multiple values.

Now I can pass the first item of each gallery to the flow without any problem.

It then sends an email with the first items of each gallery.

But actually I relate more then one item per app run.

How do I make the power app formula pass all the values I need?

My code:

TestConfirmation.Run(
galone.Selected.one;
galtwo.Selected.two;
galthree.Selected.three
)

My Flow:

Thanks for your help

Hi @Dan47 ,

You could use Json() function in canvas.

I assume I have a table in gallery like this:

If I want to pass this table(2 items) to flow , please see these steps:

1\ Create flow

2\ Add a button control in canvas and set its Onselect property to:

Test210.Run(JSON(ShowColumns(Gallery1.AllItems,"Col1","Col2"),JSONFormat.Compact))

Best Regards,

Wearsky

Hello
I used the same Json () function to pass some columns from gallery and got an array, but when i try to apply Parse Json, i get a message - Invalid type. Expected Array but got object. I dont know how to get dynamic values from there 😞 Also, to mention, i used PowerApps V2 trigger, but without inputs, i dont know if that changes anything.
