Dear LS Team,

I have two question type Multiple short text and Date question Type.

Q1. Please mention online shop that you ever buy something.
Note: plesase fill wiht "-" If you don't know the answer
A1.__________________
A2.__________________
A3.__________________
A4.__________________

Q2. When you last time to shop in online shop.[Date question with drop down]
DD MM YYYY

in Q2. I want to make a rule if all input box are filled with "-" the quest will display warning if question in not fill yet.
in Q2. If responden forget the date, the responden have choice "Im forget". So I need additional item, like Other option in radio button
question Type

1) Assuming sub-question codes "SQ001", "SQ002", "SQ003", "SQ004", place something like this in the question text or help section:
2) Add a multiple-choice question with a single option - "I forget". Then you can use relevance to hide/show the date if the multi-choice is checked. CSS could be used to make the date and multi-choice appear as one.

Hi tpartner, thanks for quick response.
The message is shown when sub question fill with "-" but it still can move to next page.
How to prevent it when all input box filled with "-"

Oh, you just said "display warning if question in not fill yet", nothing about submitting.

Something like this in the Question Validation field:

Hi Tpartner,
I just tried it. i added this script to question validation field. when i typed "-" in sub question, the input box change to
red background. Then i tried to type "abc" the input box still in red background and cannot submitted.

for your info: in put this script in text box "Validation".

but when i expand then "Advanced Setting" I found input box with label "Sub-question validation equation".

which one i should put the script?

Place it in the " Question validation equation" field.
