Hi, I would like to know if it is possible to make a upload button work in other questions. I've already made 2 question themes with the upload question button using the file upload question code(attachment below), but every time I click in this button it says: "Uncaught TypeError: upload_ is not a function at HTMLAnchorElement.onclick", I couldn't find the code that make it work properlly and I need that because my survey may need a file to most questions and if I make 1 file upload question for each question it would be too extensive.
