 <p>By default, new reference columns are added to a table as one-way references. This means they exist only as a single column within that specific table. Grist also allows you to configure a reference column with two-way references. This creates a new column in the referenced (or target) table, meaning that references between the two will be shown in both tables and remain synchronized.</p>
 <p>For example, we can make the existing reference column, <strong>Client</strong>, a two-way reference. Under the &lsquo;Column&rsquo; tab of the Creator Panel, select &lsquo;Add two-way reference&rsquo;.</p>
 <p><em><img alt="two-way-ref" src="../images/columns/two-way-ref.png" /></em></p>
 <p>This creates a new reference column in the referenced table, <em>Clients</em>. Since there can be multiple projects for a single client, the automatically-created <strong>Projects</strong> column is a <a href="../col-types/#reference-list-columns">Reference List</a>. When part of a two-way reference, updates made in one column will be reflected in the other.</p>
 <p><em><img alt="two-way-ref-2" src="../images/columns/two-way-ref-2.png" /></em></p>
+<p>Two-way references will respect if a column is a Reference or Reference List. For example, the <strong>Client</strong> column in the <em>Projects</em> table is a Reference column, meaning only one <strong>Client</strong> can be assigned to each project.</p>
+<p>The <strong>Project</strong> &ldquo;Newsletter template&rdquo; is already assigned to the <strong>Client</strong> &ldquo;Prime Builders International&rdquo;. What happens if we try to assign this project to &ldquo;ABC Construction Company&rdquo;?</p>
+<p><em><img alt="two-way-error-1" src="../images/columns/two-way-error-1.png" /></em></p>
+<p>A pop-up will appear that tells us the record is already assigned. If needed, you can reassign the record to the new <strong>Client</strong> by checking the box.</p>
+<p class="screenshot-half"><em><img alt="two-way-error-2" src="../images/columns/two-way-error-2.png" /></em></p>
+<p>To delete a two-way reference, select the reference column you wish to keep. Then in the Creator Panel, click the trash icon next to &lsquo;Two-Way Reference&rsquo;. This will delete the reference column in the target table. For example, when the <strong>Client</strong> column in the <em>Projects</em> table is selected, clicking the trash icon will delete the <strong>Projects</strong> column in the target table, <em>Clients</em>.</p>
+<p><em><img alt="two-way-delete" src="../images/columns/two-way-delete.png" /></em></p>
+<p>Alternatively, you can delete a two-way reference by selecting the column then by either selecting &lsquo;Delete column&rsquo; from the column menu or using the <code class="keys"><em>Alt</em> + <em>Minus</em></code> keyboard shortcut.</p>
+<p>Please note that two-way references cannot be used on <a href="../formulas/">Formula</a> columns.</p>
