YES, thank you Richard !
I don't understand all that but (after experimentation > I keep your post preciously) I think I can bring improvement in my sripts...

>> Most visual attributes (textFont, textStyle, textSize, backgroundColor, foregroundColor, and others) are inherited using roughly the same chain as the message path: control, background (if present), card, stack, home.

>>  get the textFont of fld 1
>> But if you've set the property to empty and want to know what value is being inherited by it, you can use the "effective" keyword:
>>  get the effective textFont of fld 1
>> That will return the value of the property nearest the control which has a non-empty value, or the engine's default if nothing in the message path has been set.
>> For example, if your field's textFont is set to empty and your card has a textFont of "Lucida Grande", then using "the effective textFont" will return "Lucida Grande".  If the card's textFont is empty but the stack's textFont is "Ariel", it will return "Ariel".  If you later set the textFont of the control to "Trebuchet", it will return "Trebuchet" regardless of the value of any subsequent objects in the chain.
