[rrd-users] gprint last_ds value

I am using a shell script to poll data from a mysql database.  
That script returns a numeric value that is being picked up properly by my data template and recorded in the rrd.
'rrdtool info' shows:
rrd_version = "0003"
step = 300
last_update = 1259633148
ds[datavalue].type = "GAUGE"
ds[datavalue].minimal_heartbeat = 600
ds[datavalue].min = 0.0000000000e+00
ds[datavalue].max = NaN
ds[datavalue].last_ds = "475.00"
ds[datavalue].value = 2.2800000000e+04
ds[datavalue].unknown_sec = 0
The value for last_ds (475.00) is the correct value returned by the script.  I want to display this value below a graph.  I use gprint with LAST and EXACT.  The value displayed is NOT 475.00.  
Is there something I'm missing?
