Hi,
if you were printing a single result, like $result, you could use that approach to set $result with the if/else structure:

if($epal>2){
//calculations
$result=376;
}

else{

$result="Error:Message";
}


but looking at your code, seems you are calculating several results, so we'd use this solution instead:


At your exit layout, create the two sections (real results, and error message). Enclose each one inside a div and set a different style for each one:

//real results

...div style="display:##displayreal##"


//here your result section..close div


//error section

..div style="display:##displayerror##"

//here your error section...close div



and now you can set at the code the display of each section according to your condition:


//calculations

if($epal>2){

$displayreal="block";
$displayerror="none";
}

else{
$displayreal="none";
$displayerror="block";

}


Please let us know if you need further help with this.


Thanks, regards
