One of my fields (Type field) I have is a drop down list with options RFC, ADM, REB. I would like to create a condition if either ADM or REB are selected from the drop-down list to require the user to select either a quarter checkbox or a month AND enter a year. Is this condition possible with the version of Adobe I am currently using? The 2nd image below shows the options that I have available. Thank You.
What do you mean by "require the user"? Do you mean you want to set the fields as Required? Do you know that's only enforced if the file is submitted?
So on your commit ( assuming you have followed the advice already given and are submitting the form) you would have to run a script to check the value of the field, and then check if your conditions are met, if they aren't then display something to the user, and if they are submit the form.
Otherwise the best you could hope for it to guide the user through alerts or showing and hiding of fields they need to fill in.
First, read the bit on Form Level Validation here:
Then lets us know exactly how you'd like the form to work when the required fields aren't filled in.
