		<summary type="html">&lt;p&gt;Created page with &amp;quot;{{TUFLOW_Message |tuflow_message=ERROR 2662 - SX groundwater connection specified for invalid layer (connecting layer larger than number of groundwater layers). |alt_msg=N/A |...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{TUFLOW_Message&lt;br /&gt;
|tuflow_message=ERROR 2662 - SX groundwater connection specified for invalid layer (connecting layer larger than number of groundwater layers).&lt;br /&gt;
|alt_msg=N/A&lt;br /&gt;
|type=[[ERROR]]&lt;br /&gt;
|message_desc=An invalid layer was specified for a SX to groundwater connection. The format for the boundary (2d_bc) GIS layer flag attribute is GW followed by a number 1-9 such as GW3 for groundwater layer 3. This message suggests that a layer was specified larger than the number of layers within the model.&lt;br /&gt;
|suggestions=Change the number following GW in the 2d_bc layer to be a valid groundwater layer or increase the number of layers represented in the model.&amp;lt;br&amp;gt;&lt;br /&gt;
For more information on 2d_bc attributes for SX to groundwater, refer to the &amp;lt;u&amp;gt;[https://docs.tuflow.com/classic-hpc/manual/latest/ TUFLOW Manual]&amp;lt;/u&amp;gt;.&lt;br /&gt;
