    problem with "File upload" form tool.

    Asked by francisflorack on September 29, 2011 at 07:18 PM

    Hi. New here. 

    I just created a form with the "File upload" form tool. I tried it, but when I try to upload a jpg (I tried several), I get the following error message:

    "You can only upload following files: pdf, doc, docx, xls, csv, txt, rtf, html, zip, mp3, wma, mpg, flv, avi, jpg, jpeg, png, gif"


    Am I doing anything wrong?

    Thank you very much.

    Hi Francis,

    I pulled out the form you mentioned however there is no upload file field included. I am unable to reproduce the said issue, once you add a file upload button you can set the file extensions that you wish to accept make sure that there is no "." before the extensions that you include.

    You may visit the following article from our user guide for more information:

    Let us know if you have questions.

    OK. sorry.

    I must have edited the form sometimes after sending my message. I created a new one and I still have the same problem:



    When i try to upload a jpg,or other supported formats, everytime, I click on the submiy button, I get the same error message.

    Thanks for your help.

    Hi Francis,

    I made a test using the new form created, I was able to upload a jpg file. This appears to be a browser related  problem, can you send us the browser type and version you are using so that we can do a further check and find out what is causing the error.

    We'll await for your response.

    May we ask for the URL of the form as well as Firefox version you are using? 

    We'll await your feedback so that we can further investigate.

    Hi Guys

    At the moment, neither type of upload button upload can be used in Firefox 7. This is an issue for which a ticket has been submitted and our developers are working to resolve it ASAP. (Please see this related thread. Sorry, I didn't remember that the thread was private.)

    In the meantime, the best we can recommend is that some sort of notice be placed on forms containing upload buttons, alerting Firefox 7 users of issue and advising them to use an alternative browser until the problem is fixed.

    Our apologies for any inconvenience caused.

    ~ Wayne

    I just tried using firefox 7 and I was able to make a successful upload with your form, francisflorack.

    Please try and see if it's still not working on your end.
