This is not the answer to "Why?" but it sort of does what you want
-----------------------------
on mouseUp
local tProperty, tValue, tTarget, tResult
put "dropShadow" into tProperty
put "color" into tValue
put the long id of button "b1" into tTarget
put fetchProperty(tProperty, tValue, tTarget) into tResult
if the result is empty then
answer "Property " & tProperty && tValue & " not found"
else
answer tProperty && tValue && tResult
end if
end mouseUp
function fetchProperty pProperty, pValue, pTarget
local tProp
put the pProperty of pTarget into tProp
if tProp is not an array then -- either single value (e.g. width) or empty
return tProp
else
return tProp[pValue] -- either array value or empty
end if
end fetchProperty
-----------------------------
Kind regards
Bernd
