Required at least one checkbox from gallery

[Thanasis]

Hello,

I am having an issue and I would really appreciate some help. 

I have build an app that has a lot of radio buttons and check boxes. What I want to to make it required that all those radio buttos and checkboxes need to be checked to be able to click the submit button . No issues there, I have created a gallery tho with a few more checkboxes that I want at least one of them to be checked, How would I make this happen. This is what I have so far

And this is the gallery  that I just created which I want the user to at least check on of those 10 (It only shows as one checkbox because  instead of a choice dropdown in a form I made them as checkboxes )

what do I have to add here to make that happen 

If(
    IsBlank(Rquestion1.Selected.Value) || IsBlank(Rquestion2.Selected.Value) || 
    IsBlank(Rquestion3.Selected.Value) || IsBlank(Rquestion4.Selected.Value) || 
    IsBlank(Rquestion5.Selected.Value) || IsBlank(Rquestion6.Selected.Value) || 
    IsBlank(Rquestion7.Selected.Value) || IsBlank(Rquestion8.Selected.Value) || 
    IsBlank(Rquestion9.Selected.Value) || IsBlank(Rquestion10.Selected.Value) || 
    IsBlank(Rquestion11.Selected.Value)|| IsBlank(Rquestion12.Selected.Value) || 
    IsBlank(Rquestion13.Selected.Value) || IsBlank(SSN1.Text) || 
    !Checkbox1.Value || !Checkbox2.Value ,
     
     Disabled,
     Edit
    )

Thank you again.

Here is a possibility if each of those checkboxes in the gallery is a separate item.

On your submit button visible or displayMode Property you could add:

If(
  CountRows(Filter(GalName.AllItems, (CheckboxName.Value)) >= 1, true, false
)

If(
  CountRows(Filter(GalName.AllItems, (CheckboxName.Value)) >= 1, DisplayMode.Edit, DisplayMode.Disabled
)

An additional note here.  What I do is to add the 5 point star shape to my required fields ( 10 x 10, red) and make them visible if the control is blank or empty and hidden if they have data.

Then for my submit I use the visibility of those icons to drive whether my submit button is clickable or disabled.   That way any more complicated formulas can be used on the visibility of the icon and all I have to do is use that when determining if the data is able to be submitted or not.

That might not work well in a gallery, but you could use it in conjunction.   Also it gives the user a visible indicator that data has to be in those fields.

Thank you @JR-BejeweledOne so much for the reply. Can you help me add this 

If(
  CountRows(Filter(GalName.AllItems, (CheckboxName.Value)) >= 1, true, false
)

to this 

If(
    IsBlank(Rquestion1.Selected.Value) || IsBlank(Rquestion2.Selected.Value) || 
    IsBlank(Rquestion3.Selected.Value) || IsBlank(Rquestion4.Selected.Value) || 
    IsBlank(Rquestion5.Selected.Value) || IsBlank(Rquestion6.Selected.Value) || 
    IsBlank(Rquestion7.Selected.Value) || IsBlank(Rquestion8.Selected.Value) || 
    IsBlank(Rquestion9.Selected.Value) || IsBlank(Rquestion10.Selected.Value) || 
    IsBlank(Rquestion11.Selected.Value)|| IsBlank(Rquestion12.Selected.Value) || 
    IsBlank(Rquestion13.Selected.Value) || IsBlank(SSN1.Text) || 
    !Checkbox1.Value || !Checkbox2.Value ,
     
     Disabled,
     Edit
    )

Again thank you so much for your your help

Are the referenced fields outside the gallery?

Hello @JR-BejeweledOne 

Yes everything except checkbox15 is outside the gallery

I think you could make this a bit simpler also.

Try this

If(
    Or(IsBlank(Rquestion1.Selected.Value), IsBlank(Rquestion2.Selected.Value), 
    IsBlank(Rquestion3.Selected.Value, IsBlank(Rquestion4.Selected.Value), 
    IsBlank(Rquestion5.Selected.Value, IsBlank(Rquestion6.Selected.Value), 
    IsBlank(Rquestion7.Selected.Value), IsBlank(Rquestion8.Selected.Value), 
    IsBlank(Rquestion9.Selected.Value), IsBlank(Rquestion10.Selected.Value), 
    IsBlank(Rquestion11.Selected.Value), IsBlank(Rquestion12.Selected.Value), 
    IsBlank(Rquestion13.Selected.Value), IsBlank(SSN1.Text), 
    !Checkbox1.Value, !Checkbox2.Value, CountRows(Filter(GalName.AllItems, (CheckboxName.Value)) >= 1, true, false) ,
     
     Disabled,
     Edit
    )
