I am writing a function that takes and array of objects and delimiter as 
arguments.  It then is supposed to take each array element's property and 
add it to a string variable.  So I should get something like:

textbox|txt_name|txt_size||radio|rad_name|rad_value||...

as output.  However, when I view the resulting string, I get all undefined 
for values.

Here is the function I'm using:

function JoinArrayOfObjects(oArray, sDelimiter) {
	var sString="", sProp, obj;
	
	for (obj in oArray) {
		for (sProp in oArray[obj]) {
			sString = sString + oArray[obj].sProp + sDelimiter;
		}
		sString = sString + sDelimiter;
	}
	return sString.substr(0,sString.length-2);
}

Can anyone figure out, please, what I am doing wrong?  I think it has to 
be a problem with the innermost statement, but I don't see what could 
possibly be wrong with it.
