If you use FF4 and cannot view the ZohoSheet online calculators, there is now a workaround. Click here!
In order to input your data, click the "Click to Edit" button. Afterwards, specify whether you are two-handing

Note: Should you accidentally delete something important, simply reload the page to restart.
