Restrict user to key in amount less than 50,000

[Champ14]

Hi,

I am building a payment app. The payment app has a form was from a Sharepoint list. There is one field for Amount. But I want that a popup will appear when the user entered a value lower than 50,000 or 50000, then upon acknowledging the popup, the value in the Amount Field will be cleared. I also want to make this field as a currency, meaning to say is when user key in 50000 it will automatically convert it to 50,000, would this be possible?

Thank you!

One way to do the popup would be to add it to whatever button/icon you're using to send that data back to the data source.

If(Value(txtAmountField.Text) > 50000,
UpdateContext({locPopup: true}),
[your formula to patch to data source or submit form here])

Then insert a rectangle, and set its Fill () property to be RGBA(0,0,0,.5). Stretch it out to cover the screen (there's your nice faded popup background). Insert whatever shape or label you want on top of that shaded popup to tell the user to correct their amount. Set the Visible() property of the shaded rectangle, and any other popup-related-controls to locPopup.

Add a close/confirm icon/button whose OnSelect property is:

UpdateContext({locPopup:false})

Now you have two buttons that toggle a variable's value to be true/false. You also have a bunch of controls that are visible based on those two controls - there's a popup!

As for formatting as currency, that's really dependent on the rest of the app/how it shows that number. Try a search for "PowerApps format as currency":

Dear zmorek,

Thanks for your response, that seems work, but is there anyway that the popup will show as sona s the user enter the amount value in the field? Instead of sfter submitting it? 

. Also, for the currency, I already tried that but for some reason it doesnt work as below, Thank you!
