OK here we go.
First i downloaded the zip file, unzipped it, moved it over to documents/sambapos5/databasetasks
Then i checked to see if the misc item task is visible in database tasks.
i then added a misc item, made sure that it is spelt correctly "Misc Item"
i can now see the misc button on my menu, but when i click on it the pop up to add price and description does not appear
