I use the {rand()} function in a hidden question in order to generate two variables, randomnumber1, and randomnumber2. I use them to show different example questions to respondents. Later, when I analyze the responses I will need to decide whether the answers of the respondents are right or wrong, depending on randomnumber1 and/or randomnumber2. Are both stored in the data set? Meaning, can I see later which of the respondents saw which randomnumber?

If you use two hidden equation questions the content of the equation (randomnumber) is saved in the results.
You should create all random numbers at the beginning of the whole survey. It helps minimize issues (at least if you allow going back in the survey).
