How to change the label of a button to the contents of an editable field?

[William de Smet]

Hi there,

I am trying to make the label of a button the same as the contents of  
an editable field.
So far I've come up with this:
set the label of button "1" to word 1 of field "1" but this returns  
the word "Field" as label of button 1.

I am stuck here but its probably very simple.
Is there someone out there who could help me?

greetings,
