I have searched all day and not found the answer to my problem.
IPGdept is a printable string. When I try to insert this entry, it gives me a syntax error at IPGdept attributes. I want to keep the / and & in there but it does not accept them. I also have | more down the line which I will probably need to escape. I tried \\ and it did not work.
