I want a calendar event to be created on submission of a form. Users are entering a date from which I would like to use Google Apps Script to create an event in a specific calendar that starts at 9am and finishes at 5pm.

I know I could ask the users to manually enter the start and finish times but I'd rather use GAS to automatically do it based on the date field. 

This is what I have currently:

```
   var vSS = SpreadsheetApp.getActiveSpreadsheet();
   var vS = vSS.getSheetByName("blah blah blah");
   var vLastRow = vS.getLastRow();
   var vStartDate = vS.getRange(vLastRow,6);
   var vStartDateValue = vStartDate.getValues();
   var vEndDate = vS.getRange(vLastRow,7);
   var vEndDateValue = vEndDate.getValues();

```

What do I need to do to get this to work?
