Noticed that in the FTS 13 pg 419 it states;
"If a script needs to use field data or some other dynamic and/or derived value as search criteria, then you
cannot use the Perform Find script step in the manner demonstrated in Activity 30.1. The criteria stored
within the Perform Find script step can only be literal values. For dynamic criteria, you must use a multistep
script routine that involves entering Find mode, setting the content of one or more search fields, and
then performing the search."
This is not necessarily true unless i am misundetrstanding the section completely.
For instance if you have a names table with a field called first_name and you can script the following and it will execute appropriatley
SetVariable $a = "the first name"
Perform Find with imbedded find critetria of names::first_name=$a
