Why do you need that? You need to use it offline?

measurements are bit off though. It lists 4,7g for 16mm marbles, but I have weighed them twice and they weigh 5,3g (10 marbles at 53g)

Hello MaddyMax,<br>I used your script on my forum. I had some issues at the begining because i don' t have any experience in computer stuff. I finally managed to make it work and, most imporant, translate it in french. After succeeding, i realized that in fact it was easy to do with a little bit of logical thinking.<br>I PM' ed Joerg to ask him if he allows me to use it on my forum, if he don' t agree i will just erase it.<br>You can see the result by clicking on my forum link in my signature. Tell me what you think about it and if i have to change something, please.<br>Thanks very, very much for the code mate.<br>Red.

Are the recommended band dimensions just the stretched part of the band or does it include the part that is used in attaching to fork and pouch? I seem to not see where this is discussed. Thanks much, Cobble
