 * Hi,
 * When displaying a single dataset using the supplied dataset.php (no mods) I get
   the following error:
 * Warning: Division by zero in …/wp-content/plugins/projectmanager/lib/core.php
   on line 1024.
 * The data for single dataset displays OK but I’m left with this error message 
   at the top of the screen.
 * Any ideas?
 * R

 * Hi,
 * Issue resolved.
 * Must have been in the middle of a “stupidity” episode!
 * On the Projects/Settings screen “Datasets per page” attribute I had “NaN” (literally–
   without the quotes of course) in the field.
 * Once I changed the field to blank or an integer – no more “divide by zero” in
   core.php errors.
 * Relief!
 * Nothing like an engine that hums along smoothly.
 * Lucky for me the “stupidity” episode has gone dormant.
 * R
 * NB: Your plugin has come along very nicely over the past several versions!!

 * I had the same problem.
 * No stupidity involved, rather we simply followed the instructions. Perhaps the
   author needs to rewrite the instructions on the Projects/Settings screen.
