Hello,
I am new to access, and I didn't find the answer to my question online, I hope someone can help
I would like to forbid a null entry in a field, only if the answer to the previous question is "yes". For instance : question 1 : "do you have cats" (yes/no) ; question 2 "how many cats do you have". If answer to question 1 is "yes", then the user must write a number in the field of question 2, but if the answer to question 1 is "no", then the field for question 2 may be null. I am guessing this could be easily done in code but I am not familiar enough with it to invent something
Thank you for your help!
