Hi Dan, I was able to replicate your problem, but then I changed the size of the BorderContainer to 550x500 and it acted normally. I even put in another input box to make the graphic even thinner and taller and it didn't make a difference. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"                xmlns:s="library://ns.adobe.com/flex/spark"                xmlns:esri="http://www.esri.com/2008/ags"                xmlns:mx="library://ns.adobe.com/flex/mx">         <fx:Script>         <![CDATA[             import com.esri.ags.Graphic;

Here are two ways of looking at it. If you want to add the attribute for LAND_AC6 only when none of the other fields have any attributes, then use this. Function FindLabel ( [LTSA_LOT] , [LTSA_BLOCK] , [LTSA_PA4] , [LTSA_PLAN] , [LAND_AC6] )    if ( Len ([LTSA_LOT]) <> 0) then     str = [LTSA_LOT] & " - "   end if   if ( Len ( [LTSA_BLOCK] )  <> 0) then       str = str + [LTSA_BLOCK] & " - "   end if   if ( Len ( [LTSA_PA4] )  <> 0) then          str = str +  [LTSA_PA4] & " - "     end if     if ( Len( [LTSA_PLAN] ) <> 0) then     str = str +   [LTSA_PLAN]   end if     if ( Len( [LAND_AC6] ) <> 0) then     str1 =  [LAND_AC6]    end if   if (Len(str) > 0) then     FindLabel = str   else     FindLabel = str1   end if End Function If you want to add the attribute for LAND_AC6 if one or more of the other fields don't have any attributes, then this should work Function FindLabel ( [LTSA_LOT] , [LTSA_BLOCK] , [LTSA_PA4] , [LTSA_PLAN] , [LAND_AC6] )   dim found   found = True    if ( Len ([LTSA_LOT]) <> 0) then      str = [LTSA_LOT] & " - "   else       found = False    end if   if ( Len ( [LTSA_BLOCK] )  <> 0) then        str = str + [LTSA_BLOCK] & " - "   else       found = False   end if   if ( Len ( [LTSA_PA4] )  <> 0) then           str = str +  [LTSA_PA4] & " - "   else        found = False     end if     if ( Len( [LTSA_PLAN] ) <> 0) then     str = str +   [LTSA_PLAN]   else        found = False   end if     if ( Len( [LAND_AC6] ) <> 0) then     str1 =  [LAND_AC6]    end if   if found then     FindLabel = str   else     FindLabel = str & vbNewLine & str1   end if End Function ...
