Using concatenation for key in object?

[VirtualVirgin]

I am trying to name the key for some key value pairs in an object, and I am stuck on concatenation.

		local matrixTableReturnObject = 
		{
		 	name + "inputNameArray" : inputLabels,
			name + "outputNameArray" : outputLabels.outputNameArray,
			name + "outputLabelArray" : outputLabels.labelArray,
			name + "outputPanelArray" : outputLabels.panelArray,
			name + "outputLabelPanelArray" : outputLabels.labelPanelArray,
			name + "outputClickPanelArray" : outputLabels.clickPanelArray,
			name + "buttonMatrixArray" : buttonMatrix.buttonMatrixArray,
			name + "inputOutputMatrixArray" : buttonMatrix.inputOutputMatrixArray
								
		};

and I am getting this error:

Interface:! GUI_Factory_Methods.js (277): Found '+' when expecting ':'

This is inside an inline function which has an input parameter "name".
How can I get it to concatenate properly to use as a key?

local matrixTableReturnObject = {};

matrixTableReturnObject[name + "inputNameArray"] = inputLabels;
matrixTableReturnObject[name + "outputNameArray"] = outputLabels.outputNameArray;
// etc.
