DAOPHOT standalone to DAOPHOT/IRAF

Hi,
I have run DAOPHOT, the stand-alone version to get instrumental magnitudes. I am now trying to calibrate the standard stars as detailed in sections 3.6 to 3.10 of "A User's Guide to Stellar CCD Photometry with IRAF".
I have created the imsets file, which looks like this:
I have called this file 'standstars'
I have an observing parameter which is this:
I've called it 'obsparam'
The output from ALLSTAR looks like this:
In this example, I have artificially changed the names of the stars. I hope I don't have to do this for all the standard stars. I just don't quite know what IRAF is expecting. I would like to simply use the ID that DAOPHOT/ALLSTAR give it. I have four of the outputs from ALLSTAR - one for each filter.
Finally, I have the input list, which is simply :
Then these are the parameters I'm using for mknobsfile:
And the rest are the defaults.
But mknobsfile gives me this error:
Image set: 1 Label: PG1047+003 has no data
And so forth for pg1047+003(A-C)
What am I missing here?
Thanks!

P.S. I'm running this in PyRAF 1.9, IRAF 2.14, on a Mac 10.5.8
