Understanding Uninitialized Variables— changing code below the line

Tell us what’s happening:
My code meets all the conditions except “do not change code below this line”; however, I haven’t changed any code below the line! What else do I need to do? Thanks

Your code so far

// Initialize these three variables
var a = 6;
var b = 15;
var c = "I am a String!";

// Do not change code below this line

Thanks for your reply. I’m still confused— I tried initializing (a,b,c) to (5,10,“I am a”), then modified the variables so they meet the conditions (6,15,"I am a String!). It’s still telling me that I haven’t met the condition “Do not change code below the line” even though I haven’t changed any code below the line.
