note Limbic~Region [rob_au], <br /> Instead of adding it, I have updated the node to remove <i>exists</i> in that section as it was not necessary. It did not occur to me that novices might see <i>exists</i> as improper with an array and total miss using a string as an index. <p> While your point is well taken, I believe "Autovivication Pitfalls and How To Avoid Them" deserves to be a tutorial all to itself. </p> <div class="pmsig"><div class="pmsig-180961"> <p> Cheers - [Limbic~Region|L~R] </p> </div></div> 371938 371991
