<p>Hi There,</p>
<p> </p>
<p><Newbie> I am still learning the BIRT\Eclipse reporting tools, hence my new(bie) question to the experts.</p>
<p> </p>
<p>I have created an optional parameter to display vendor details for a user to select at run time.</p>
<p> </p>
<p>I have the Parameter created as a dynamic list box, allowing multiple values to be selected. I have selected the working data set, selected the value column and display column. My problem is that when I try to preview the report, the parameter list box has "Null Value" as the only selectable item.</p>
<p> </p>
<p>The items I am slecting are string values. So I am aware I may have issues with the IN clause, I just need to get past this stop first.</p>
<p> </p>
<p>!HELP!</p>
