<tr class="#1#">
<td >#2#</td>
<td>#3#</td>
<td style="background-color: yellow;">#4#</td>
<td>#5#</td>
<td>#6#</td>
<td>#7#</td>
<td>#8#</td>
<td>#9#</td>
<td>#10#</td>
<td>#11#</td>
<td>#12#</td>
<td>#13#</td>

<td>#2#</td>
<td>#3#</td>
<td>#4#</td>
<td>#5#</td>
<td>#6#</td>

"Row Template 2 Condition" - use based on PL/SQL Expression
'#DOCUMENT#' is null
The "Row Template 1" is to be show only if Column "DOCUMENT" is not null, otherwise "Row Template 2" is to be show if Column "Document" is null. I have test various examples:
'#4' is null, '#4#' is null and '#DOCUMENT#' is null. Without effect. Only "Row Template 1" is showing.
Can anybody help me?

Hi,
null in conditions would return no value rather than 'null' - you can catch this by using an empty string - so:
'#4#' = ''Andy
