What language are you working in? The syntax will change slightly depending on the specific language, but most of the popular languages allow you to access elements in a list/array like this: aList[0] where 0 indicates the first element of the list. If you are working in python, for example, the function definition would look like this

def getFirstValue(aList):
    return aList[0]
