Hi everyone, I am building up a survey for a time-use diary analysis, so I have several blocks of questions about what respondents did during day. For every activity they insert (one different block everytime they pass on to a new activity), I ask them the timing, so that at each block I have the question "untill which time did you do last activity the respondent indicated he/she was doing?" With piped text everything works fine untill there, but I would like to set a costum validation, i.e. I would like to impose the timing of the new activity to be after the time they indicated as the ending time of the previous activity. Anyway, when I ask qualtrics for a custom validation, I am propmted with this screen ! where I cant impose any reference to other questions and I have to select a choice from the options I put myself as possible answer to the question (i.e possible hourse of the day). Instead I would like to have: Validation will pass if the following condition is met: IF "Q37 ECC.." "*SELECTED CHOICE OF Q37*" is greater or equal to "*the time selected as the ending one of the preceding activity*" By the way, it is the same problem I have if I try to put a display logic: instead of having a square starting with an "IF"+*little square indicating the selected question* I only have the little square indicating the selected question, as you can see by the screen below: ! I have no clue about why I cant impose the validation I would like (from the forum it seems it is something I should be able to do without any java vel similia, anyway any solution is accepetd!). Thank you in advance!

@C882, If I were you, I would use flatpicker.js with noCalendar, enableTime, and minuteIncrement options for time inputs.

On custom validation, if you want to compare greater than or equal to a previous question then Q37 has to be a text entry question and you have to pipe in the value from the previous text entry question you want to compare it to (e.g. ${q://QID1/ChoiceTextEntryValue}. Since they are times, you need to make sure they are in a format that they can be compared.As for Display Logic, the "IF" is implied.
