What more precision do you need? Joffm has explained everything.
You create an equation question with a random number between 1 and 2. Loads of descriptions on how to do this in the forum (once you know it works you'll hide this question for the respondents not to see it.
Then you create two versions of the same question.
Q1a with the order of answer options like 1, 2, 3, 4, 5
Q1b with the order of answer options like 5, 4, 3, 2, 1
Via relevance equations you show or hide these questions, depending on the choosen random number. E.g. if the random number is 1, you show Q1a, if the random number is 2 you show Q1b. Or vise versa, your choice.
This should give you roughly 50% of respondents that have seen the order 1, 2, 3, 4, 5 and roughly 50% that have seen 5, 4, 3, 2, 1.
To analyze the data you just need to rearrange your columns again the analysis program of your choice (Excel, SPSS, PSPP, Stata, whatever...).

- Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
- Always provide a LSS file (not LSQ or LSG).
