Why is my code not working?

How can I get it to display the message if the x meets the requirements?

Code

input('Enter a test grade between 0 and 100: ')

if (x >= 90)

disp('The student earned an A.')

elseif (x >= 65)

disp(The student passed the test_11)

else

disp('The student did not pass the test.')

end

I get this error

Invalid expression. Check for missing multiplication operator, missing or unbalanced

delimiters, or other syntax error. To construct matrices, use brackets instead of

parentheses.

The cause of the error is that the second disp line doesn't have quotes:

disp(The student passed the test_11)

It should be:

disp('The student passed the test_11')

But to get the program to work, you'll want to assign the output from input to the variable x:

x = input('Enter a test grade between 0 and 100: ');
