Body
Well for starters there something wrong here: <pre><code> if (list1Ptr == NULL && list2Ptr != NULL) { list1Ptr = list2Ptr; head = list1.head; break; } </code></pre> If you are done traversing list1 then what you want is to point the last node of list1 to point at list2. <code>list1Ptr = list2Ptr;</code> is doing nothing of that. It is merely changing the local variable's value. Same for this part: <pre><code> else if (list2Ptr == NULL && list1Ptr != NULL) { list2Ptr = list1Ptr; head = list1.head; break; } </code></pre> This is a bad of doing things: <code>list1Ptr->data > list2Ptr->data && list1Ptr != NULL && list2Ptr != NULL</code> If list1Ptr becomes NULL then if you try to access NULL->data there is surely going to be trouble(since generally the expression will be executed left to right). Also: <pre><code> else if (list1Ptr->data > list2Ptr->data && list1Ptr != NULL && list2Ptr != NULL) { typename List<T>::Node* temp = list2Ptr; list2Ptr = list2Ptr->next; temp->next = list1Ptr; } </code></pre> There is something really wrong here too. You first store list2ptr in a temp. Then you move list2ptr to the next node in list2. But why make <code>temp->next = list1ptr</code>? You should be re thinking that part out. And same for the next else block. Best. EDIT: Alright, let's see what more can be done: Here is the psuedo code I suggest you use: <pre><code>func(list1,list2): ptr1 = list1.head ptr2 = list2.head declare pointer curr if(ptr1!= NULL and ptr2!=NULL){ if(ptr1->data < prt2->data) {curr = ptr1 ptr1 = ptr1->next head = curr } else{ curr = ptr2 ptr1 = ptr2->next head = curr}} else{ head = whichever one is not NULL, or NULL if both of them are and return } while(ptr1 != NULL and ptr2!=NULL){ if(ptr1->data < ptr2->data){ curr->next = ptr1 curr = ptr1 ptr1 = ptr1->next continue} else{ curr->next = ptr2 curr = ptr2 ptr2 = ptr2->next continue} } if(ptr1 == NULL) curr->next = ptr2 else curr->next = ptr1 </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
