My problem is deleting a node from linked list.

I have two structs :

typedef struct inner_list 
{
    int count;
    char word[100];
    inner_list*next;
} inner_list;
typedef struct outer_list
{
    char word [100];
    inner_list * head;
    int count;
    outer_list * next; 
} outer_list;

My problem is in deleting a node from outer_list linked list. For example when user entered aaa to delete, delete function should find the node with outer_list->word = aaa and delete this node and reconnect the list again. I tried the below code to do this. but After finding and deleting I'm losing the list. I don't know what's wrong. Please notice that outer_list have also a linked list of inner_list inside.

void delnode(outer_list *head,char num[100])
{
outer_list *temp, *m;
temp=head;
while(temp!=NULL)
{
    if(strcmp(temp->word==num)==0)
{
if(temp==head)
{
head=temp->next;
free(temp);
return;
}
else
{
m->next=temp->next;
free(temp);
return;
}
}else
{
m=temp;
temp= temp->next;
}

}
printf(" ELEMENT %s NOT FOUND ", num);
}

What are your ideas about this?
