OK, I figured out the problem, but not the solution.  The output is actually 
from a SQL query.  The output looks like this (when echoed):

Serial_Number
TLO000003

It is getting the field name and the field value as two lines. So there is a 
newline before the TLO000003 not a space.  So I tried 
Serial_Number=${Serial_Number#\n} and Serial_Number=${Serial_Number#\r} but 
neither seemed to work.  Any suggestions?

In fact a better thing would be to get the result from mysql without the field 
name - just the value as a string.  Any ideas how?

Thanx again.
