Posted on by Community Power Pla... Microsoft Employee

Hello,

I am trying to create a button which will display an error message when a single or multiple checkboxes haven't been selected inside of a gallery. I tried using:

IfError(Checkbox7_2.Value=false, Notify("Question Unanswered",NotificationType.Error))

But i haven't been able to get it to work.

Hi @Anonymous,

Do you want the button to show Error Information if the checkbox not be selected?
I think you could change IfError to If:
If(Checkbox7_2.Value=false, Notify("Question Unanswered",NotificationType.Error)).

I have tested as next screenshot:
Button1.OnSelect:If(Checkbox1.Value=false,Notify("Question Unanswered",NotificationType.Error))
And the result is if the checkbox not be selected,it will show the error information:

HI @Anonymous,

Do you want to display the error message when multiple Checkboxes have not been selected within your Gallery?

Based on the needs that you mentioned, I think the CountRows function and Filter function could achieve your needs.

I have made a test on my side, please take a try with the following workaround:

Set the OnSelect property of the "Detect" button to following:

If(
CountRows(Filter(Gallery1.AllItems, Checkbox1.Value=true)) <= 1, /* <- Checkbox1 represents the Checkbox control within my Gallery*/
Notify("Question Unanswered", NotificationType.Error)
)

On your side, you should type:

If(
CountRows(Filter(YourGallery.AllItems, Checkbox7_2.Value=true)) <= 1, /* <- Checkbox7_2 represents the Checkbox control within your Gallery*/
Notify("Question Unanswered", NotificationType.Error)
)

In addition, if you want to display an error message when a single or multiple checkboxes haven't been selected inside your gallery, please take a try with the following formula:

If(
CountRows(Filter(YourGallery.AllItems, Checkbox7_2.Value=true)) < 1, /* <- Checkbox7_2 represents the Checkbox control within your Gallery*/
Notify("Question Unanswered", NotificationType.Error)
)

Or

If(
CountRows(Filter(YourGallery.AllItems, Checkbox7_2.Value=true)) = 0, /* <- Checkbox7_2 represents the Checkbox control within your Gallery*/
Notify("Question Unanswered", NotificationType.Error)
)

Please check the attached GIF screenshot for more details:

Best regards,

Kris
