Adding a fixed choice conjoint question in Qualtrics

Link to R demo files in video:

In this video I show two ways to create a fixed choice question in a Qualtrics conjoint survey:
1) One approach is to copy and paste the html code to create a conjoint question table that is the same for every respondent. This only enables you to put a fixed choice question before or after the main conjoint questions (but not within them).
2) The other approach is to import a custom design of experiment into Qualtrics that has a fixed choice question across all respondents. This approach allows you to put the fixed choice question anywhere within the main conjoint questions.
Approach 1:
00:52 - Adding a fixed choice question by copy-pasting from the survey preview
02:33 - Changing the fixed choice levels
03:29 - Changing images in the fixed choice question
04:29 - Making the copy-pasted table an actual choice question
Approach 2:
06:38 - Adding a fixed choice question within the main conjoint questions
08:10 - Editing the design file in R

Hi John, I tried to make a conjoint design by a trial of DesignXM Qualtrics. I can not save the conjoint design. There is an error. it occurs because of my trail plan? Thank you for your advice!
