Script to combine multiple scripts - google-apps-script

Question

The script below does not work as expected. Can anybody help me to check if I missed anything? Gives me error TypeError: Cannot call method "getValue" of null. I run the script again and it goes through but doesn't change anything on the file.
Below are the parts of the script and how they should work:
First part is to automatically get data from the CSV Reports in Keyword Inspector. I have this "Settings" sheet where it has the password, email, and URL Links to the reports. > first part works fine.
Second part is to paste data in the "GetCSV" sheet. But first we must check if we have data in the first three columns, if there is any existing data we must move all data to the right. We paste what we get from the .csv file in "GetCSV" sheet, in Column 2, Row 2. In Column 1, row 2 we paste date and time format starting from A2 down to the last row with data:
setValue(Utilities.formatDate(new Date(), "GMT", "MM-dd HH:mm AM/PM"));
Third part, we copy the same data we updated to its final destination "Data" sheet, starting from the first empty row.
I am not very savvy with the Java script and I already have this script in place, I just need to modify it a bit based on my needs.
