[Javascript] Form focus

[George Pitcher]

Shawn,

Sorry about the spanner I threw into your 'Thousands separator' task last
week.

I finally got round to working with the earlier stuff you sent me and it was
fine but only worked when I was changing field contents. By changing
onchange to onfocus, I was able to have the same functuonality as I have in
Filemaker.

Thanks for setting me off in the right direction.

Cheers

George in Oxford
