Problem regarding an AS3 program

[Arnabjit5E24]

I stuck on a program which I want to run for checking whether the given answer is right or wrong. In the program, I ask the user whether an equation is linear or non-linear. when the user type the answers in the output window, by default it marks them as incorrect, but after that when I reset them, for the same answers it evaluate the answers correctly. Can you please help me out with this? I would highly appreciate your help. Thank you.

c1.visible = false;
f1.visible = false;
c2.visible = false;
f2.visible = false;
c3.visible = false;
f3.visible = false;
c4.visible = false;
f4.visible = false;
reset.visible = false;
check.addEventListener(MouseEvent.CLICK, chek);
reset.addEventListener(MouseEvent.CLICK, killreset);
function chek(evt: MouseEvent): void {

if (q1.text == "" && q2.text == "" && q3.text == "" && q4.text == "" ) {
c1.visible = false;
f1.visible = false;
c2.visible = false;
f2.visible = false;
c3.visible = false;
f3.visible = false;
c4.visible = false;
f4.visible = false;

} else {
if (q1.text == "linear" || q1.text == "LINEAR" || q1.text == "Linear") {
c1.visible = true;
} else {
f1.visible = true;
}
if (q2.text == "non-linear" || q2.text == "NON-LINEAR" || q2.text == "Non-linear") {
c2.visible = true;
} else {
f2.visible = true;
}
if (q3.text == "linear" || q3.text == "LINEAR" || q3.text == "Linear") {
c3.visible = true;
} else {
f3.visible = true;
}
if (q4.text == "non-linear" || q4.text == "NON-LINEAR" || q4.text == "Non-linear") {
c4.visible = true;
} else {
f4.visible = true;
}
}
check.visible = false;
reset.visible = true;
}

function killreset(evt: MouseEvent): void {
c1.visible = false;
f1.visible = false;
c2.visible = false;
f2.visible = false;
c3.visible = false;
f3.visible = false;
c4.visible = false;
f4.visible = false;
reset.visible = false;
check.visible = true;
q1.text = "";
q2.text = "";
q3.text = "";
q4.text = "";
}

If you want to see the output video I can also enclose that.

Hi.

I'm not sure what the problem is. Can you provide more details:

Anyway, you can use the toLowerCase method in the if statements instead of verifying several scenarios. Like this:

else
	{
		if (q1.text.toLowerCase() == "linear")
			c1.visible = true
		else
			f1.visible = true;
		
		if (q2.text.toLowerCase() == "non-linear")
			c2.visible = true
		else
			f2.visible = true;
		
		if (q3.text.toLowerCase() == "linear")
			c3.visible = true
		else
			f3.visible = true;
		
		if (q4.text.toLowerCase() == "non-linear")
			c4.visible = true
		else
			f4.visible = true;
	}

Please let us know.

Regards,

JC

I hope you can access the fla file by the aforementioned link. In this quiz, my desired answers should be "linear, non-linear, linear, non-linear" respectively, but when I put these as my answers it is not showing me the correct output. Kindly help me with that portion. Thank you.
