    <p>My program simulates a video store. In my list there are multiple copies of some videos. If I try to rent a video and the first copy of that video in the list is already rented, my program fails to continue checking to see if the other copies are available (a film is available if custId is '0000'). Take a look at the text file from where the list gets its members for a better understanding of what i'm describing:</p> <p><img src="https://i.stack.imgur.com/Ntp6m.png" alt="enter image description here"></p> <p>Could anyone take a look and let me know if they spot an issue? Any help is appreciated, thanks.</p> <p><strong>Code from main</strong></p> <pre><code> try { int index = 0; bool found = false; while (!found) { if (strncmp(filmId,filmList.getAt(index).number,6) == 0 &amp;&amp; strncmp("0000",filmList.getAt(index).rent_id,5) == 0)//If that film is rented by NO customer { found = true;//customer can rent it strcpy(newItem.number,filmId);//copy filmId into newItem filmList.retrieve(newItem);//copy the struct in our orderedList with the same filmId/copy into newItem filmList.remove(newItem);//delete the struct with same filmId/copy as newItem from the orderedList strcpy(newItem.rent_id,custId);//update info in strcpy(newItem.rent_date,rentDate);// newItem to show strcpy(newItem.return_date,dueDate);// that it has been rented filmList.insert(newItem);//put NewItem into list, effectivily replacing the removed item. cout &lt;&lt; "Rent confirmed!" &lt;&lt; endl; } else { if (strncmp(filmId,filmList.getAt(index).number,6) &gt; 0 || strncmp("0000",filmList.getAt(index).rent_id,5) &gt; 0) { ++ index; } else { throw string ("Not in list"); } } } } catch (string s) { cout &lt;&lt; "\n***Failure*** " &lt;&lt; s &lt;&lt; endl; } </code></pre> <p>Let me know if more code is required from any other parts of the program. </p>

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.
