Using a while loop to output a cube root?

In the attached document, I cant seem to get the actual cube root value to come out. Could someone please look at my script file.

You're not updating the estimate. Your function's loop repeatedly uses the user inputted value for intialEstimate rather than updating it as the calculation progresses. You need to fix line 6 so that the estimate is updated for each loop iteration.
