Read the instructions again for this group.? They are on the group's webpage, and in the email message you received when you joined the group.? Files and pictures must never be attached to messages in the group.? Yahoo automatically removes them.
Upload your schematic to the "Temp" folder:
? ? neo/groups/LTspice/files/%20%20Temp/
Navigate to that folder first, then click the "Upload" button.? If it's a schematic, upload the .ASC file, not a picture of the schematic.? If your schematic uses other symbols or models that did not come with LTspice, then first zip them into one .ZIP file (that's .ZIP!? not .RAR or .7z or something else), and upload that .ZIP file.
Can you trace through the lines of the truth table, probing all the voltages, to see why it does not satisfy the truth table?
