more linked list printing problems

[musicmancanora4]

Sorry for posting again guys but i have fixed up teh string copies to copy the data into each struct variable. But still when i traverse through the linked list it does not print out anything after it reads the file. For some reason it may not be copying at all or something any idea's?

i think its because currentCat variables is pointing to NULL rather then a node but im unsure how
to fix it cuz it wont print any of the data which is being loaded

int loadData(GJCType* menu, char* menuFile, char* submenuFile)
{
   /*pointer for malloc*/
   CategoryType *newCat, *currentCat, *prevCat;
   
   

   /*declaration of variables*/
   int CountNoLines = 0;
   char temp[LINE_LENGTH];
   
   /* variables for tokenizer for menu file*/
   char *catID;
   char *catType;
   char *catName;
   char *catDescription;
   char *delim;
   
   /* declare file pointers to files*/
   FILE *f1;
   FILE *f2;
   
   
   /* opening the menu and submenu for reading*/
   f1 = fopen(menuFile, "r");
   f2 = fopen(submenuFile, "r");
   
   /* check to see if the filuse exists*/
   if(f1 ==NULL || f2 == NULL)
   {
      /* check whether both files have existed or typed in correctly*/
      if(f1 == NULL && f2 == NULL)
      {
      
         printf("Both files do not exist %s %s\n",menuFile,submenuFile);
      }
      /* check for each file existance*/
      else if (f1 == NULL)
      {
         printf("%s does not exist\n\n",menuFile);
      }

while(fgets(temp, LINE_LENGTH, f1)!=NULL)
{
   newCat = NULL;
   prevCat = NULL;
   currentCat = NULL;

   newCat = malloc(sizeof(CategoryType));

   if(prevCat == NULL)

   {

In the above snippet prevCat is initialized to NULL each time the loop starts to the conditional of the if statement will always be true and the else statement will never be reached.
