I have the following text in the toolbar of a form:
<div>
<h5 style="color: <<WorkOrder.Customer.EntityAlert.Color_Foreground>>; background-color: <<WorkOrder.Customer.EntityAlert.Color_Background>>; border: 2px solid <<WorkOrder.Customer.EntityAlert.Color_Background>>; box-shadow: 3px 3px 5px #888888; padding: 10px;">
<<WorkOrder.Customer.EntityAlert.Alert>>
</h5>
</div>
This displays an Alert Message for a customer like below:

The problem I have is that if the customer does not have an alert message it still shows a shadowed box, where the alert message would go, like this:

Is there a way to condition the html so that it only displays the message if WorkOrder.Customer.EntityAlert actually has a value?
Thanks,
Jim
