I am very recent to salesforce.com so i don't have much idea about it. I have a requirement in which requires that a text field be created or removed depending on a pick list value. For example I have 2 fields "Issues" and "Comments". according to the requirement when if i choose the value 'others' then the field "Comments" Should be visible, otherwise the field should be removed. I don't think the above scenarios can be accomplished by using Formula Editor or Validations. Is there any way in which the above mentioned can be achieved?
