replacing eval

i want to access a element of a object using the name, i original taught that eval would do the job but its been depricated so adobe suggent using syntax this['blah' + i ]
i have tried this but it aint working

            trace(i )     // is equal to name
            trace(  printLabelArray[pi].dispensingItemPrintElementdrug.templateElementText.text)  // prints John
                        trace(  this["printLabelArray[pi].dispensingItemPrintElement"+i]) // i get undefined here
                        trace(  this["printLabelArray[pi].dispensingItemPrintElement"+i+".templateElementText.text"] ) // and here
