<p>Hi Filippo,</p>
<p>to achieve this, you can use the "Arithmetic Expressions" by specifying the table column of an index table. This will return a list of the values of each row in that column. However, if the target is an index field that can hold only one value, you must specify an index (starting at 0) to return only the value of a particular row.</p>
<p>Example:<br>
You have a table "Line Items" with 2 columns, ID and GL Code:<br>
 </p>
<table border=1 cellpadding=1 cellspacing=1 style="width:500px;">
<tbody>
<tr>
<td>ID</td>
<td>GL Code</td>
</tr>
<tr>
<td>1</td>
<td>000-4000</td>
</tr>
<tr>
<td>2</td>
<td>000-5000</td>
</tr>
</tbody>
</table>
<p><br>
<br>
With the expression <code>DW_LINE_ITEMS[LINE_GL_CODE][0]</code> you get the value "<strong>000-4000</strong>", because index 0 is applied and the value of the first line is returned. Whereas with the expression <code>DW_LINE_ITEMS[LINE_GL_CODE][1]</code> index 1 is applied and the value of the second line is returned: "<strong>000-5000</strong>".</p>
