Set custom field to required depending on value of a select list

Question

Hi I have the following problem,

I want to add a script in workflow validation that does the following:

if a select list has any value that starts with "yes" another custom field is required (must not be empty)

How can I accomplish that?

many thanks

With a simple scripted validator:

(! cfValues["Select List"].value?.startsWith("Yes")) || cfValues["Other Field"]

(untested - if it doesn't work break it down and do it piece by piece in the condition tester).

Can also be done with a behaviour which will show the user that the field is required before they click submit, but more complex
