Thanks Nick. I have had partial success. I think my problem may be that we use Week A and B instead of 1 and 2. Is there any way to change this? I have used the sims import to varying degrees of success and the file contains this

<Record>
<Name>R1</Name>
<MainTeacher>Mr H Solo</MainTeacher>
<Description>Ict</Description>
<Name1>1Mon:3</Name1>
<YearGroup>Year 12</YearGroup>

I have changed teh 1Mon bit from my output of AMon, but don't think that should be right or does it take a moment to propegate?
