ReportWarning Rule

Need help with a ReportWarning rule. I have attached the rule I'm working on. The rule looks at agent's who codes and entering their information from an external file. What I need it to do is report a warning if their is no agent code (pr1) matching in the external file.

{

Rule("OnJobStart");

}

if(FusionPro.Composition.isPreview == true || FusionPro.inValidation == true)

numRecsExtDF = externalDF.recordCount;

for (recordWalker=1; recordWalker <= numRecsExtDF; recordWalker++)

if(externalDF.GetFieldValue(recordWalker, 'Who Code') == Field("pr1"))

returnStr += '<b>' + externalDF.GetFieldValue(recordWalker, 'Address')+'</b>';

returnStr += '<br>';

returnStr += externalDF.GetFieldValue(recordWalker, 'City');

returnStr += ' ';

returnStr += externalDF.GetFieldValue(recordWalker, 'Zip');

returnStr += '<br>';

else

{

ReportWarning("Who Code " + Field("pr1") + "not found");

}

I don't have your data file to test with, but basically you want to finish looping through the records, then check to see you if found anything. Try this:

if (FusionPro.inValidation)
   Rule("OnJobStart");

var returnStr = "";
var numRecsExtDF = externalDF.recordCount;
for (recordWalker=1; recordWalker <= numRecsExtDF; recordWalker++)
{
   if(externalDF.GetFieldValue(recordWalker, 'Who Code') == Field("pr1"))
   {
       returnStr += '<b>' + externalDF.GetFieldValue(recordWalker, 'Address')+'</b>';
       returnStr += '<br>';
       returnStr += externalDF.GetFieldValue(recordWalker, 'City');
       returnStr += ' ';
       returnStr += externalDF.GetFieldValue(recordWalker, 'Zip');
       returnStr += '<br>';
   }
}

if (!returnStr)
   ReportWarning("Who Code " + Field("pr1") + "not found");

return returnStr;
