Regarding Input text fields

Question

This is about fill in the blanks in flash 8 as2. In this i used input  text fields and three buttons.In first frame i used multiple input text  fields and a submit button. After filling all the blanks we click on  submit button then in the second frame we will show the result like if  the blank is correct it should change the color to green and if it is  wrong it should change to red.and in the frame i have check button when  we click on it will display all the answers. And when we click on  analyse button we have to display the answer which the user types and  the correct answers.
And my problem is when we click on submit there is no difference in the blanks color all are in black only and i have assigned red to the wrong answer and green to the correct answer.
and script on submit button is
on (release) {
    gotoAndStop("Bl1");
    if ((_root.Bl.txt1 == "abc1") && (_root.Bl.txt2 == "abc2") && (_root.Bl.txt3 == "abc3") && (_root.Bl.txt4 == "abc4")) {
        _root.Bl.txt1.textColor = 0x006600;
        _root.Bl.txt2.textColor = 0x006600;
        _root.Bl.txt3.textColor = 0x006600;
        _root.Bl.txt4.textColor = 0x006600;
    } else {
        _root.Bl.txt1.textColor = 0xFF0000;
        _root.Bl.txt2.textColor = 0xFF0000;
        _root.Bl.txt3.textColor = 0xFF0000;
        _root.Bl.txt4.textColor = 0xFF0000;
where "Bl" is the movie clip name and "txt1","txt2","txt3","txt4" are the var names for input text fields
Please help........

Answer 1

You are concatenating the conditions it will only work if all are true or  all are false
on (release)
    gotoAndStop("Bl1");
    if (_root.Bl.txt1 == "abc1")
        _root.Bl.txt1.textColor = 0x006600;
    else
        _root.Bl.txt1.textColor = 0xFF0000;
    if (_root.Bl.txt2 == "abc2")
        _root.Bl.txt2.textColor = 0x006600;
    else
        _root.Bl.txt2.textColor = 0xFF0000;
    if (_root.Bl.txt3 == "abc3")
        _root.Bl.txt3.textColor = 0x006600;
    else
        _root.Bl.txt3.textColor = 0xFF0000;
    if (_root.Bl.txt4 == "abc4")
        _root.Bl.txt4.textColor = 0x006600;
    else
        _root.Bl.txt4.textColor = 0xFF0000;
You can also run a for loop for optimizing the code further.
