Dear Sir or Madam

I have looked through the support site trying to find an answer to my question but did not yet succeed.
The thing is that I get a lot of reports from people registering for an event for which they first have to register.
For registering i use easy profile. There is quite an amount of details needed from the user.
Also upload fields are required. But when something goes wrong during this (complex) registration, like Captcha issues or field format errors, the upload fields and password fields are emptied again and the user isn't always aware of that.
Is there a way to keep those fields populated with the date already provided by the user?

Thanks a lot
Best Regards
