Some of these questions may have only been asked once :smile:

How do I make a Likert-scale?

There's a number of ways, but the most popular one is to write rating_button 5 in the type column and put the lower pole in the choice1, the upper pole in the choice2 column. That way you'll see the choice1 and the choice2 text, and in between 5 buttons. If you want to anchor each level, you would probably prefer mc_button, where you would put all choices in the columns choice1 to choice5.

How can I show someone else what I've got so far, i.e. let someone look onto and fill out the survey?

You have to create a run, put the survey in a run, create a "New test code" (in the side bar) and send the other person the test link.

How can I make a survey with many connected pages (that cannot be returned to once turned) instead of a long list of questions?

Insert items of type "submit" wherever you want a page break. Users will only progress once all preceding items have been answered.

Is the formr-Output well compatible with SPSS?

You can export Excel tables which are easy to get into SPSS. There’s also CSV and TSV, both of which can be imported into SPSS too. There are a few niceties to using R (e.g. auto-aggregation of scales and computation of alphas, you can simulate data based on the item tables if you want to test your feedback), but it isn't necessary at all. And of course, using R you have wide array of choices to export data to CSV, Stata, Excel, SPSS etc. The new version of the formr package will also automatically label your items in SPSS if you use formr_results() and haven::write_sav().

What does this error message mean "There were problems with openCPU."?

This is a very general error message. It means something went wrong while executing R code, that you, the study's creator, have written. You can use R code in many places including showifs, values, labels and in many places in the run (e.g. feedback, emails etc.). This error message is not very helpful in finding and fixing the bug. If you see it yourself, you're probably not logged in into your admin account and not using a test code. If you set the session you're in to test mode, you'll get a more informative error message. For security reasons we don't show this informative error messages to anyone. If your users see this error message, they hopefully copied the time the error occurred as well. Using this information, we can find out why they saw this error.

Is it possible to create blank rating buttons (without numbers on them)?

It's possible, just add the class blank_button in the class column for the respective item.
