Upon installing (or more accurately trying to install) a floor this
morning, pieces just wouldn't clip together. Occasionally, they did,
but this seemed to be whimsical. Tapping it together did no good
whatsoever. It was maddening!

Any thoughts as to what I'm doing wrong - and I *know* I'm doing
something wrong.

The wood was leaning up against a wall in their boxes for all of 24
hours, could this be it? By laying flat now solve the problem if this
is it?

Thanks in advance...
