Sorry, I meant to say, I checked the file out first, then modified, then checked in.

I am doing that bit right.

When I check for differences in the form, it says they are identical.

It is comparing:
$cms600/form/form1.sca WITH
c:\develop\cms600\form\form1.sca

Could it be that $cms600 is looking in the wrong place?

Thanks for reply
