thanks michael,

you were right. when you close the popup you can paste into the field. now i can continue checking the script out. :-)

update; it let me paste in the number however the script didn't generate the blade with the right radius. it used the number prior to the paste. so its somehow not accepting the paste, even though it shows it in the input box. perhaps when you hit the x to close the popup anything after that is not being read.
