How do I show participants a file they uploaded through the File upload question type?

I added a line of code with piped text, that should show participants a picture that they uploaded just before in the survey, through the file upload question. First participants upload a picture. With piped text you can conjure up the url of this uploaded file. On the next page, I show a picture, where the image source is the piped text that refers to the URL of the uploaded file. See the code below (I replaced all '<' with '[' so you can read the code instead of seeing a non-loading picture). [div][br][/div] [ img src="${q://QID649/UploadedFileLink}" style="width: 300px; height: 210px;"] [div] [/div][div][br][/div] That way I show participants the picture they just uploaded. This approach works when I pretest the survey. However, after adding this line of code, the survey keeps giving error messages whenever i want to change something else in the survey (Error: Cannot save, Your browser cannot connect to Qualtrics, and you have X unsafed questions. Check your network connection and try again). Does anyone know how to fix this? Is there something wrong with this line of code?
