I'm still learning the basics, so please excuse the simple question!

I have this actionscript up in a Flash 8 frame:

stop();
var percent=(points/90)*100;
var greeting1 = "";
var greeting2 = "";

if (percent<66) {
greeting1 ="Bad Luck.";
greeting2 ="You failed. You need 66% to pass.";
}
if ((percent>=66) or (percent<=80)){
greeting1 = "Good Try!";
greeting2 = "You passed!";
}

if ((percent>=80) or (percent<=90)){
greeting1 = "Very Good Work!";
greeting2 = "You passed with Merit!";
}

if (percent>=90){
greeting1 = "Excellent Job!";
greeting2 = "You passed with Distinction!";
}

trace (percent);


When I test it out, a percent of 0% returns the greetings "very good work" and "you passed with merit". Please tell me why! This is doing my head in! Am I doing this completely wrong? Tx!

The logical OR operator in actionscript is "||" (OR was deprecated the last time I programmed in AS)
and your logic was a little wonky it needs to be a logical AND

so the logic would read "if (greater than OR equal to 66) AND (less than 80) then" otherwise everything more than 66 would match the "greater than 66" comparison.

reworked and tidied code.

if (percent<66) {
greeting1 ="Bad Luck.";
greeting2 ="You failed. You need 66% to pass.";
} else if ((percent>=66) && (percent<80)){
greeting1 = "Good Try!";
greeting2 = "You passed!";
} else if ((percent>=80) && (percent<90)){
greeting1 = "Very Good Work!";
greeting2 = "You passed with Merit!";
} else if (percent>90){
greeting1 = "Excellent Job!";
greeting2 = "You passed with Distinction!";
}

Thanks so much chrishirst! It works now

Here is the finished article - just in case you were interested!

It's only the second bit of Flash I've attempted so it's very very clunky - I hope it works properly!
