% Number of inputs: 3
% If expression (e.g., u1 ~= 0):
u1 == 1
% Elseif expressions (comma-separated list, e.g., u2 == 2, u3 == 3):
(u2 == 2) && (u3 == 3)
% Show else condition:
Ensure that each condition within the Elseif expressions field is properly formatted using logical operators like && (AND) or || (OR).
Separate multiple elseif expressions with commas, if there are more than one.
Here’s the corrected entry based on your input:
If expression:
u1 == 1
Elseif expressions:
(u2 == 2) && (u3 == 3)
Ensure there are no extra spaces or unbalanced parentheses.
Double-check variable names and ensure they match the input names used in your Simulink model.

Hi Maya,
You are getting this error because the square brackets and '&&' are not allowd in IF block. The allowed opertators are <, <=, ==, ~=, >, >=, &, |, ~, ( ), unary-minus. So the modified equation as per this would be as below.
(u2==2) & (u3==3)
I hope this helps!

Hello Aman,
I want the logical AND to perform. "&" will give other result.

I think you must delete all spaces in the second condition:
u2==0&u3==2
