I need to send a new invitation to people that already submitted the survey.
They must correct wrong answers.
Is this possible?

I think this isn't possible wihtout any workaround.

Please search the forum and take a look at this thread:
www.limesurvey.org/index.php/Can-I-do-th...-survey-answers.html

I suspected this.
I'm trying to understand what happens when you save an incomplete survey.
The table "lime_saved_control" is populated with a new line, and I think that the fields have this meaning:
scid: auto incremental field
sid: survey id
srid: the id of the line in lime_survey_XXXXX
identifier: username given when you save incomplete surveys
access_code: md5 hash of the password
email: given email
ip: ip
saved_thisstep: question number when you restart the survey
status: it seems always "S"
saved_date: saving date
refurl: survey url

I created a new line like this and, adjusting lime_tokens_xxxxx and lime_survey_xxxxx for a fresh token, I wrote a link similar to the one you have in the re-invitation mail, trying to get access to a submitted answer.
But I can reach only the last (greetings) page with a saved_thisstep > 1, or the first page of the survey with saved_thisstep=0 and then immediatly the last.
There is something wrong but I don't know what!

It will be easy in 1.8 (soon to come now).
You will have to:
1- Reset tokens invitation to not Sent
2- Reset answers to not completed
==> Will work only on non anonymous surveys with "Allow Persistence" option set.

In LS 1.72, you don't have the "Reset answers to not completed", so thiw would require:
* export of tokens
* vvexport of answers
* deactivate/activate survey in order to erase answers
* import answers from VVimport but Add the 'import as incomplete answers' option
* import tokens

@pierpaolo: Can you please test and report back if this works? If so we'll add some words to the manual.

It works on my trial survey.
But wait until I will submit it to my real users with their real surveys.

I have added this to the wiki.

@pierpaolo, can you please add your version to the "tested with" part!? Thanks!

In my 1.71+ I have "import as not finalized answers" instead of "import as incomplete answers"
I added version number to the wiki

well, I tested it with real surveys, but I've found a problem. When I try vv-export I'm dropped to the main page of the survey whithout the normal download window, even if the url seems fine (localhost/limesurvey/admin/admin.php?act...export&sid=98271); there is no way to save the file.
I think that there is something in the survey, because a simple trial survey worked.
This survey is so great that it was splitted in five actions, each linked to the next.

Did you test this with the latest release?

If not please upgrade to the latest release. A lot of errors have been fixed in the latest release.
More information:
- Download latest release
- Upgrade instructions

If so please open a ticket at the bugtracker and attach your survey. You can mark your ticket "private" so that only the developers will be able to take a look at it.

Afterwards please post the link to the bugtracker so we can follow the progress.

You can also switch on debug mode by adding the following line to your config.php file:


Are there any errors reported?
