Technically you have unbalanced parentheses because you do not have a closing parenthesis in front of each comma that separates the value pairs of the function, and you do not have an opening parenthesis after each such comma.

You do not need to put parentheses around each pair of values or even around any specific parameter value inside the function's opening and closing parentheses. Remove all the parentheses except the first and the last that enclose the list of value pairs, and it should work.
