EM supports the function "if(test,do_if_true,do_if_false)" so that you can perform conditional logic or tailoring. This function can be nested to do the equivalent of "if { } else if { } else { }". EM will let you know if the parentheses are not balanced (e.g., you are missing a closing right parenthesis), or if you have any extra right parentheses. You should try to count the parentheses as you compose long nested if statements, save it, check for syntax errors, and fix them if any are found. Let's check together the below example.
