How can I use a checkbox value to determine whether to clear other elements in App Designer?

I am trying to make the app clear values from edit fields if their corresponding checkbox is unchecked.

When I try to run the code below, I don't get any errors, but nothing happens either.

p = checkbox

ef = text edit field

r,b,f = numeric edit fields

function ClearButtonPushed(app, event)
    p=[app.p1.Value,app.p2.Value,app.p3.Value,app.p4.Value,app.p5.Value,app.p6.Value,...
       app.p7.Value,app.p8.Value,app.p9.Value,app.p10.Value,app.p11.Value,app.p12.Value];
   
    ef=[app.ef1.Value,app.ef2.Value,app.ef3.Value,app.ef4.Value,app.ef5.Value,app.ef6.Value,...
        app.ef7.Value,app.ef8.Value,app.ef9.Value,app.ef10.Value,app.ef11.Value,app.ef12.Value];
    
    r=[app.r1.Value,app.r2.Value,app.r3.Value,app.r4.Value,app.r5.Value,app.r6.Value,...
       app.r7.Value,app.r8.Value,app.r9.Value,app.p10.Value,app.p11.Value,app.p12.Value];
   
    b=[app.b1.Value,app.b2.Value,app.b3.Value,app.b4.Value,app.b5.Value,app.b6.Value,...
       app.b7.Value,app.b8.Value,app.b9.Value,app.b10.Value,app.b11.Value,app.b12.Value];
   
    f=[app.f1.Value,app.f2.Value,app.f3.Value,app.f4.Value,app.f5.Value,app.f6.Value,...
       app.f7.Value,app.f8.Value,app.f9.Value,app.f10.Value,app.f11.Value,app.f12.Value];
   
    for n=1:12
        if(p(n) == 0)
            ef(n) = ' ';
            r(n) = 0;
            b(n) = 0;
            f(n) = 0;
        end   
    end
end

Jacob - your arrays like

ef=[app.ef1.Value,app.ef2.Value,app.ef3.Value,app.ef4.Value,app.ef5.Value,app.ef6.Value,...
        app.ef7.Value,app.ef8.Value,app.ef9.Value,app.ef10.Value,app.ef11.Value,app.ef12.Value];

are just values and not handles to the objects that you want clear/reset. You might want to try storing the handles in each array like

ef=[app.ef1, app.ef2, app.ef3, app.ef4, app.ef5, app.ef6, ...
        app.ef7, app.ef8, app.ef9, app.ef10, app.ef11, app.ef12];

and then access these handles as

    for n=1:12
        if(p(n).Value == 0)
            ef(n).Value = '';
            r(n).Value = 0;
            b(n).Value = 0;
            f(n).Value = 0;
        end   
    end

I don't know if the above will work...and I suspect that there are alternatives to this...but give it a try.

That worked perfectly, thank you. Also helped me find some mislabeled handles in the arrays when I was deleting all the ".Value"s
