My survey starts off asking the user's name and their partner's name.

Can questions in the survey then refer to their partner by their name? In other words can I capture the first name field and carry it forward to future questions? e.g. 'What does Samantha think about drunk drivers?' I'm not good at coding by the way!

The Expression manager can help you.

Let's assume your question is named "partnername" (=question code). Then you can use the following code in your questions:

What does {partnername.shown} think about drunk drivers?

You will find addional examples here:
=> docs.limesurvey.org/Expression+Manager+HowTos

/edit: actually it should also work just with your question code. The .shown is not necessary, but a (bad?) habit of mine.

Ah yes! The Expression Manager covers what I want to do - thanks!

Now I expect I'm being really dumb here, but when I try that, I get a red highlighted box around the question code that I entered in curly brackets, and when I hover over that it says 'undefined variable'. I expect it's something really basic I've missed ...

You checked for typos? Embarassingly that's the most common cause in my case, so perhaps that's the reason for you as well? You have to use the exact name of the question given in the question code (check also for capital letters!). If you have problems using the EM, you could also use the somewhat older function of insertans. That's the icon with the lemon in curly brackets....

Another line of approach (but actually this would imo lead to another error message): You inserted this question *after* the question of the partner's name? Otherwise it would not work, because the name has not yet been given.

Yes, the lemon icon did it for me! Thanks again!

camelchops, maybe you can help others by improving our manual. E. g. by posting an example here: docs.limesurvey.org/Expression+Manager+E...tions+for+LimeSurvey
