Hi Rich,

First an important bit of information : 'find' only
works on fields in a stack, not a variable.
But you can use offset, lineOffset, wordOffset and
itemOffset to find data inside variables.

In the above case, I'd use itemOffset.
--
on returnInField
  global tVar
  global itemNum
  put the tet of me into theStringToFind
  set the itemDelimiter to "|"
  put itemOffset(theStringToFind,tVar) into itemNum
  put itemNum
end returnInField

Allow me to encourage you to use a clear naming scheme
for variables, as this will help you track errors and
read your own scripts more quickly.
One guideline that I know a number of Revolutionaries
follow is the Scripting Style Guide :
<http://www.fourthworld.com/embassy/articles/scriptstyle.html>

Hope this helped,

Jan Schenkel.
