"Part 4/4 Variable defaults". "private var myBlankString:String = null;" is avalid answer, chnge question text.
P.S. sorry for those messages, but I think it is better to be sure, that all valid answers work.
Part 3/5 Flash and Programming Basics. "What symbol do you type to create a single line comment?".
Part 4/21 Rite of Passage. "What is the symbol for creating a single line comment?". Right answer is "/" not "//". "//" is not a symbol or charachter.
Same for "Part 11/21 Rite of Passage".
Also singlequotes are valid, but not accepted in "Part 11/11 trace()"
Part 3/8 Using Strings and Variables. Don't let use single quotes. Only Double quotes allowed. You should write about it in question or accept either answers.
"Part 7/7 Variables and Math
Here is the last practice section before we move on to variable types. What is the final value of variable 3?"
There is no variable 3. I belive you men thirdVariable. As programmer you know that those are not the same.
