The file disappeared
A file isn't saved until you click Submit Assignment. If you left the page first, attach the file again, then submit.
It says "images," but I uploaded a PDF
The limit line under the upload button counts every file you attach, including PDFs and Word documents, even though it says "images." You can attach up to 10 files.
Which files can I upload?
Word (.doc, .docx), Excel (.xls, .xlsx, .csv), PowerPoint (.ppt, .pptx), PDF, images (.jpg, .jpeg, .png, .gif), and .zip files.
My PDF from the generator looks wrong
Open the PDF and check it before you upload it. In "Select one or more" questions, check at least one box. See Filling in your templates.
I uploaded the wrong file
After you submit, the module locks, and our team can reopen it. See Resubmitting an assignment.
