Hello all,
In the snippet included below, I’m hoping the second line of the
scoreTitleMarkup will take no vertical space. If you comment out that line,
you’ll see that it *does* take no space, but when it’s included, so is the 25mm
spacing that is [I thought] conditional on the presence of a ‘testB’ property
in the property.
Where is my code going wrong?
More precisely, how can I make it work as intended? =)
Thanks,
Kieren.
