Hey ebrahem anwar,

When you're doing challenges, be sure to do exactly as the challenge tells you to do. You don't have the proper variable nor the proper string in the "printf" line. The challenge tells you to print "First name: " and then the user's first name. The print line should be:

console.printf("First name: %s", firstName);

Hi Anwar, You have to write the "Marcus Parsons " explaination because what they asked in the question that exactly you have to present otherwise it gives you error. So please follow. Anwar, you have written very good and it is appreciated but last thing forgotten. Please correct it and enjoy JAVA coding.

^^^yup, what they said^^^, PLUS notice that in your code you declared a String variable called firstName, but later in the code you try to reference it as firstname (i.e. without the camel case capital 'N'). I'm fairly new to Java myself, but already I've realised that making sure variable names always match exactly when you reference them is REALLY important. I'm getting into the habit of copying and pasting variable names directly from where I declare them when I need to reference them later in my code...it totally cuts out any typing errors or mismatches (btw you can't right click copy / paste in the practice exercises, but the Ctrl + C / Ctrl + V keyboard shortcuts work fine :-)

Hope that helps some...
