//Function to validate the entry made by user in User Form

function validateEntry(){

//declare a variable and set the reference of active google sheet

var myGooglSheet= SpreadsheetApp.getActiveSpreadsheet(); //declare a variable and set with active google sheet

var shUserForm    = myGooglSheet.getSheetByName("User Form"); //delcare a variable and set with the User Form worksheet

var ui = SpreadsheetApp.getUi(); //to create the instance of the user interface to show the alert

//Assigning white as default background color

shUserForm.getRange("C6").setBackground('#FFFFFF');
shUserForm.getRange("C8").setBackground('#FFFFFF');
shUserForm.getRange("C10").setBackground('#FFFFFF');
shUserForm.getRange("C12").setBackground('#FFFFFF');
shUserForm.getRange("C14").setBackground('#FFFFFF');

}

datasheet.getRange(blankRow, 1).setValue(shUserForm.getRange("A1").getValue()); //Staff/DJ Name

datasheet.getRange(blankRow, 3).setValue(shUserForm.getRange("C1").getValue()); //D.O.B

// date function to update the current date and time as submittted on
    datasheet.getRange(blankRow, 5).setValue(new Date()).setNumberFormat('yyyy-mm-dd h:mm'); //Submitted On

//get the email address of the person running the script and update as Submitted By
    datasheet.getRange(blankRow, 6).setValue(Session.getActiveUser().getEmail()); //Submitted By

ui.alert(' "New Data Saved - DJID #' + shUserForm.getRange(A1).getValue() +' "');

shUserForm.getRange("C4").clear();
shUserForm.getRange("C6").clear();
