form code for context

From my form's comments text:

<!-- Reuploading a file will produce warnings that cause Semantic Forms to fail if the user does not check "Ignore any warnings". The file might be uploaded, but "lost" due to the file name not being passed to the form, and the identical error repeating when the user gets warnings again if they try to reupload the file. This can also happen, for example, when the file has been previously deleted, possibly because it was previously "lost" in an identical circumstance, or a similar circumstance such as the one above where users continue to upload files without realizing they need to click a second button to "Save page". I'm sure there are other ways this particular bug can be triggered. --><nowiki />

Notice that this issue is reached when other bugs are are encountered that cause a user to try uploading their file again.
