Hi,

I have some check boxes in a gallery within a new form, I would like to check if these checkboxes have been selected when a 'cover' option has been selected, this is to prevent any blank data being passed through when the form is submitted. Please see my code below, I am currently just getting a Blank or false return for the checkbox2.value check? I have tried Gallery1.Selected.Checkbox2.Value but this returns false too when the check boxes are selected!

togCoverRequired.Value = true && Checkbox2.Value = false,

Notify(

"You have selected for cover but not ticked any time slots",

NotificationType.Error,

8000

Thanks in advance.

hey @BS10

you can try this:

If( togCoverRequired.Value = true && CountRows(Filter(Gallery1.AllItems, Checkbox2.Value = true)) = 0, Notify( "You have selected for cover but not ticked any time slots", NotificationType.Error, 8000 ) )

Let me know if my answer helped solving your issue.

If it did please accept as solution and give it a thumbs up so we can help others in the community.

Hi @mmbr1606,

Thank you for the fast response. I have tried this below and also added a text label with the code
CountRows(Filter(Gallery1.AllItems,Checkbox2.Value = true)) = 0
but this is always returning as true so it's accepting the form even if the checkboxes are not checked?

Thank you

@mmbr1606 - Apologies I should have mentioned, I have multiple other if statements so I just added this before the SubmitForm property, does this make a difference?

Hi @mmbr1606,

Thank you, I have just tried this but unfortunately the notification error "you have selected for cover but not ticked any time slots" appears even if checkboxes are ticked. Just thought I would mention that this does go through successfully if the togCoverRequired is set to no (false) but then the if statement isn't being ran.

Hi @mmbr1606,

I've just done a bit more testing, I added a text label and added the code below but the number just stays at 0. When I go into the text property on the text label, it says the actual amount of checkboxes that have been ticked?

Thanks
