7,952 PointsWhat is the "proper variable spacing"?? Please see below -
<?php $studentOneName = 'Dave'; $studentOneGPA = 3.8;
$studentTwoName = 'Treasure'; $studentTwoGPA = 4.0;
//Place your code below this comment if ( $studentOneGPA == 4.0 ){ echo $studentOneName, 'made the Honor Roll'; } else { echo $studentOneName, 'has a GPA of', $studentOneGPA; }
if ( $studentTwoGPA == 4.0 ){ echo $studentTwoName, 'made the Honor Roll'; } else { echo $studentTwoName, 'has a GPA of', $studentTwoGPA; }
?>

13,608 Pointsecho $studentOneName, 'has a GPA of', $studentOneGPA;
This line previews as: 'Davehas a GPA of3.8'
echo $studentOneName, ' has a GPA of ', $studentOneGPA;
Whilst this previews as: 'Dave has a GPA of 3.8'
You just need to add spaces either side of the string between the variables.
