The problem with an equivalent piece of code has just caught me out - see if you can spot it (I couldn't for ages, even in the debugger):

So, here's Maximum Bob's quiz:-

(No cheating, no prizes)

* Set up our local variable:
local sTest

* Now, here's the easy bit:
sTest = "Ole Ftang"

* Tell everyone what the result is:
messageBox("sTest is currently: " + sTest)

* Now change the value;
stest = "Biscuit barrel"

* Tell everyone what the result is now:
messageBox("sTest is now: " + sTest)
