zmiana skryptu

Witam mam problem. otrzymałem od kolegi skrypt ale chciałbym dodać rubryke TYTUŁ oraz rubryke FullInfo. wiecie taki generator postów robię podobny do generatora z exsite. rubrykę potrafię zrobić ale nie wiem jak połączyć ją z generuj by tekst sie przetworzył. pokaże oco mi chodzi na foto

to mój kod:

<script type="text/javascript"> 
         function doStuff() 
         { 
         var txt = ""; 
         document.getElementById("gen").value = ""; 
          
         if (document.getElementById("boxart").value != ""){ 
         txt = "[center][img]"; 
         txt += document.getElementById("boxart").value; 
         txt += "[/img][/center]\n\n"; 
         document.getElementById("gen1").value += txt; 
         } 
        if (document.getElementById("boxart").value != ""){ 
         txt = "[center][img]"; 
         txt += document.getElementById("boxart").value; 
         txt += "[/img][/center]\n\n"; 
         document.getElementById("gen").value += txt; 
         }
          

         if (document.getElementById("info").value != ""){ 
         txt = ""; 
         txt += "[center][img=http://www.fototube.pl/pictures/inf46oeff0000ffffff352129yelloew0062.gif]\n"; 
         txt += document.getElementById("info").value; 
         txt += "[/center]\n\n"; 
         document.getElementById("gen1").value += txt; 
         } 

        if (document.getElementById("info").value != ""){

         txt += document.getElementById("info").value; 
         txt += "[/quote][/center]\n\n"; 
         document.getElementById("gen").value += txt; 
         } 

         if (document.getElementById("sshot1").value != ""){
