[Koha] Change the opac-detail.tt

Hi everybody, We need to modify the opac-detail.tt? Why? Take a look: If we made a search(looking, for example, a title) on KOHA (No opac), we have the following results: Title, subtitle and the Metion (fields 245 a,b,c. That is ok. When we do the same using OPAC We have: Title and the SUBTITLE (245 b) does not appears and the 245 c neither Do we have to setting something on the OPAC screen o what? -- *Luis Moisés Rojas P.*
