how to avoid deselcting by clicking?

[Richard Hillen]

Hello,

there is a field with some selected text.

I want to get the selected text by clicking at a button.

So I wrote in the buttonscript:

on mouseup
get the selectedtext of fld "xxx"
put it
end mouseup


Why is there nothing put? How to avoid deselecting by clicking at the button?

Thanx.

Richard Hillen.
