Re: alzheimers and confused

AND seems correct to me. If you want to generate an error when the file is not a jpeg file then the file name must not contain jpg AND must not contain jpeg. If either jpg OR jpeg is present then no error should occur. Be careful when using the !not operator with logical condition operators, the logic becomes more complex.
