Dependent field is not working

I have created doctype “Candidate Details”. Which is linked to another doctype “Manpower Requisition Form” through field “post_applied_for”.

Candidate Details also has field “post_name” which is dependent on field “post_applied_for” and show post_applied_for.job_title as value which is specified in field options.

post_name field dependancy works properly when Candidate field value is “New Candidate Details 1”. But when it’s value changed post_name doesn’t work.

Please check attached screenshot.

Thank you.

Got what was problem.

Candidate details name field was used to hold candidate name. name field is primarily used for auto name hence it was conflicting. Hence change name field name to candidate_name.
