No features found. Could not verify expression.

Error Message

When attempting to verify or execute an advanced Java Script labeling expression, the following error occurs:

"No features found. Could not verify expression."

Cause

The labeling expression parser expects a field name to be enclosed in square brackets. In Java Script, the square brackets refer to functions such as an array, which results in the error.

Solution or Workaround

Code:
function FindLabel ( [Name] )
{
  var strArray = [Name].split(" ");
  return( strArray[0] );
}

Code:
Function FindLabel ( [Name] )
  dim pArr
  dim pStr
  pArr = split([Name]," ")
  pStr = pArr(0)
  FindLabel = pStr
End Function
