Thanks; you're absolutely right - doh!  It's just amazing that this ever

 From the manual:

DOUBLE[(M,D)] [UNSIGNED] [ZEROFILL]

M is the total number of decimal digits and D is the number of digits

You have created your columns with a max width of 7, out of which 6 are 
decimals, but you are trying to insert a number with 8 digits.
