Working with LimeSurvey

Can I do ... with LimeSurvey?

Probably. LimeSurvey is an amazingly powerful and customizable piece of software, but it may be daunting at first. If you have specific wishes that aren't covered in any of the manuals or FAQs, feel free to contact the SurveyServer team for help.

I can't make group/survey description text justify to the left with the UTwente template

The problem is that the template and the editor have different default justifications.

The editor expects left-justification to be the default, and therefore does not add information to the text on how it should be justified. However, the template defaults to centre justification, so if no information is given, text is centre-justified.

To make text justify to the left, you have to specifically set the text to be left-justified. See the below video (Dutch) for an example on how to do this.

Can my colleague/student-assistant and I work together on the same survey?

Yes. You have two options, you can share your account, or have a new account created.

Sharing an account is simple, just give your colleague your LimeSurvey login credentials. If security is a concern, you may want to give him/her specific rights.

In order to give someone specific rights to your survey, that person needs to have an account, and both your accounts need to be in the same group. The SurveyServer team can do this for you.

When all accounts are created and placed in the same group, it is up to you to set specific permissions for the extra accounts. See the below video (Dutch) for an example on how to do this.

Can I add an extra logo to my survey?

Yes. See the below video for an explanation and example on how to do this.

I get an error when trying to upload a token CSV

Do you get the below error? (Or one that looks much like it?)

CDbCommand failed to execute the SQL statement: SQLSTATE[HY000]: General error: 1366 Incorrect string value: '\x94rgen' for column 'firstname' at row 1

The problem is that the csv contains one or more special characters (é,ð,ñ, etc.) which are not correctly represented in the file's character set. The solution is to store the CSV with UTF-8 as the character set, which handles just about every character ever invented.

However, you can not do this in Microsoft Excel. Most other spreadsheet software, including Google Docs and OpenOffice, either stores CSV in UTF-8 by default or gives you the option to select a character set (encoding). Copy/paste the token list from Excel into the other software, and then safe it (setting encoding to UTF-8 if neccesary). This should fix character encoding issues.
