ActionScript String Concatenation in for loop - actionscript-3

Question

So I am struggling with loops.
I have a mobile app with dynamic controls that I add from a sqlite database, it is a list of questions and based on the question type, I add the relevant type of control to the page along with the question, this all works fine.
I then loop through all the controls looking for answers, so I can loop through 60 quesitons and return the values from the relevant textboxes, checkboxes and toggle switches.
The for loop runs like this
if (displayObject is DisplayObjectContainer && currentDepth < maxDepth)
{
for (var i:int = 0; i < DisplayObjectContainer(displayObject).numChildren; i++)
{
traceDisplayList(DisplayObjectContainer(displayObject).getChildAt(i), maxDepth, skipClass, levelSpace + " ", currentDepth + 1);
if (displayObject is TextInput ||displayObject is CheckBox || displayObject is Label || displayObject is ToggleSwitch )
{
if(displayObject["id"] =="QuestionText"&& (i==0))
{
if(displayObject["text"] != null)
{
questionString= (displayObject["text"]);
trace ("Question: " + questionString);
}
}
else if (displayObject["id"] == "QuestionResponse")
{
if(displayObject["text"] != null)
{
answerString = (displayObject["text"]);
trace ("Answer: " + answerString);
}
}
else if (displayObject["id"]== "CheckboxResult")
{
if(displayObject["selected"] != null)
{
checkboxAnswer = (displayObject["selected"]);
trace ("Check / Toggle: " + checkboxAnswer);
}
}
}
}
}
My question is, the results I get back look like this;
questionstring value
answerstring value
checkbox value
what I want is
questionstring value, answerstring value, checkbox value
I cannot for the life of me see how I get these values into 1 row.
Any tips appreciated

Trace just prints info to the console mainly for debugging if you really want all of that on one line in the console you just need to create a string and then add "Question: " + questionString + " Answer: " + answerString + " Check / Toggle: " + checkboxAnswer to the string after you have found them all and then call trace with your string you made. something like this
var mystring:String
mystring="";
if(displayObject["id"] =="QuestionText"&& (i==0))
{
if(displayObject["text"] != null)
{
questionString= (displayObject["text"]);
mystring += "Question: " + questionString;
}
}
else if (displayObject["id"] == "QuestionResponse")
{
if(displayObject["text"] != null)
{
answerString = (displayObject["text"]);
mystring += "Answer: " + answerString;
}
}
else if (displayObject["id"]== "CheckboxResult")
{
if(displayObject["selected"] != null)
{
checkboxAnswer = (displayObject["selected"]);
mystring += "Check / Toggle: " + checkboxAnswer;
}
}
trace(mystring);
