Maintain item field change when another field is choice

[Dario_C]

Hi guys, I have an urgent task to do. I have an item Keep with "type" field with value to point to service_offering, each service_offering has in the endorseable option for different item.

When the user chooses the type (service_offering) I must show the description of the current choice of service_offering under an information box or inside another field (I don't know).

If I try with the catalog script, do I have to make a glide record on service_offering and take the description field? Or is there another simple method to show description on field type? 

Thanks in advance !

To show the description of the service offer each time the user chooses another, i needed to do a Script Include for retrieve the description with glide record  and  then an catalog client script  with an call back function.
