Oliver, Theo: > ~ '^[0-9]+$'
Actually, I usually do: ~ '^[0-9]+\.?[0-9]*$' ... to include decimals. However, the above assumes that there is at least a "0" before the decimal; it would be nice to adapt it to matching a leading decimal (i.e. .057 ) as well. Can't see any easy way, though ... -- Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
