Change stack in openStack

In accord with advice on the web site, I have a sub-stack which contains
data to be saved between runs of the application. When opening the main
stack, I want to retrieve some defaults and last user data and populate
the main stack fields. This is a fragment of the code:
global gPinions, gSpurs
set hilite of button "Pinion" to false
[more "set" statements deleted]
set hilite of button "Rollout" to true
put empty into field "poss rollout"
put 0.5 into field "Tolerance"
go stack "Gears"
[more lines deleted]
I tried painfully building the lines until I could isolate where it fell
over, as the debugger seems arcane. It is when you add the code
<<go stack "Gears">> when it produces this error, apparently from one
of the tool stacks, not mine. This is the message:
• There was an Execution Error at 9:30:23 PM
Error description: if-then: error in statement
Revolution User Interface Error: Object: button id 1137 of group id 1136
of card id 1002 of stack
"/Elsewhere/Users/davidv/Applications/Revolution 1.1 OS
if it is not empty then
The same code works perfectly if I put it in a button and execute it
What is going on here please?
