This is a question about the trigger when inserted from CF7 into Google spreadsheet.

//FormApp.getActiveForm()

function reverse() {

    var spreadsheet=SpreadsheetApp.getActiveSpreadsheet(); // Container Bound Script
    varsheet_add=spreadsheet.getActiveSheet();

    if(sheet_add.getName()=="sheet1"){

        // retrieve a spreadsheet
        varsheet=spreadsheet.getSheets()[0]; // Get by specifying sheet 1
        var lastRow=sheet.getRange(sheet.getMaxRows(), 1).getNextDataCell(SpreadsheetApp.Direction.UP).getRow();

        range=sheet.getRange(lastRow, 1, 1, 13);
        varcurrentRangeValues=range.getValues();

        varsheet3=spreadsheet.getSheets()[2]; // Get by specifying sheet3

        var numRows = currentRangeValues.length;
        var numColumns=currentRangeValues[0].length;

        sheet3.insertRows(2,1);
        sheet3.getRange(2,1,numRows,numColumns).setValues(currentRangeValues);

    }

}
