<div class="content wysiwyg-content">
I have a linked table that has &quot;Project Number&quot; and &quot;DVD#&quot; as two of the fields and another linked table that has &quot;Project Number&quot; and &quot;Box Number&quot; as two of the fieds. &nbsp;One database tracks all of the information stored on DVD and the other database tracks all of the archived paper documents.<br />
<br />
I am trying to create a query that will combine the two and reflect changes to either table. &nbsp; &nbsp;I get an error message that &quot;Project Number&quot; could refer to either table. &nbsp;I need to have one complete list of project numbers combined from both databases.
