Conditional if loop for addition of three consecutive numbers in app designer interface

Greetings to all, I am trying to solve this code in app designer: If the sum of three consecutive numbers is >75 I should get the word 'OK' otherwise 'NO', this is the interface with the names and the respective code: thank you!

    x1=app.EditField.Value
    x2=app.EditField_2.Value
    x3=app.EditField_3.Value
    x4=app.EditField_4.Value
    if x1+x2+x3>75
        app.EditField_5.Value=disp('OK');
    elseif x2+x3+x4>75
        app.EditField_5.Value=disp('OK');
    else app.EditField_5.Value=disp('NO');
    end

if (x1+x2+x3)>75
 app.EditField_5.Value=disp('OK');
  elseif (x2+x3+x4)>75

You need to use parenthesis ( ) in the if-else condition as shown

Not needed. Addition takes place before >:

1. Parentheses ()
2. Transpose (.'), power (.^), complex conjugate transpose ('), matrix power (^)
3. Power with unary minus (.^-), unary plus (.^+), or logical negation (.^~) as well as matrix power with unary minus (^-), unary plus (^+), or logical negation (^~).NoteAlthough most operators work from left to right, the operators (^-), (.^-), (^+), (.^+), (^~), and (.^~) work from second from the right to left. It is recommended that you use parentheses to explicitly specify the intended precedence of statements containing these operator combinations.
4. Unary plus (+), unary minus (-), logical negation (~)
5. Multiplication (.*), right division (./), left division (.\), matrix multiplication (*), matrix right division (/), matrix left division (\)
6. Addition (+), subtraction (-)
7. Colon operator (:)
8. Less than (<), less than or equal to (<=), greater than (>), greater than or equal to (>=), equal to (==), not equal to (~=)
9. Element-wise AND (&)
10. Element-wise OR (|)
11. Short-circuit AND (&&)
12. Short-circuit OR (||)

Try it this way (untested and not using disp):

x1 = app.EditField.Value
x2 = app.EditField_2.Value
x3 = app.EditField_3.Value
x4 = app.EditField_4.Value
if x1 + x2 + x3 > 75
    app.EditField_5.Value ='OK';
elseif x2 + x3 + x4 > 75
    app.EditField_5.Value = 'OK';
else 
    app.EditField_5.Value = 'NO';
end

Or you can combine the first two:

x1 = app.EditField.Value
x2 = app.EditField_2.Value
x3 = app.EditField_3.Value
x4 = app.EditField_4.Value
if (x1 + x2 + x3 > 75) || (x2 + x3 + x4 > 75)
    app.EditField_5.Value = 'OK';
else 
    app.EditField_5.Value = 'NO';
end

Attach your .mlapp file if you need more help.
