Got this now, after correcting the brackets:
SELECT
case when
date('2006-10-14', '+' || (strftime('%Y', 'now') - strftime('%Y', '2006-
10-14')) || ' years') <= date('now') then
case when
strftime('%d', 'now') > strftime('%d', '2006-10-14')
then
((strftime('%Y', 'now') - strftime('%Y', '2006-10-14')) * 12 +
(strftime('%m', 'now') - strftime('%m', '2006-10-14'))) - 1
else
(strftime('%Y', 'now') - strftime('%Y', '2006-10-14')) * 12 +
(strftime('%m', 'now') - strftime('%m', '2006-10-14'))
end
else
case when
strftime('%d', 'now') > strftime('%d', '2006-10-14')
then
(strftime('%Y', 'now') - strftime('%Y', '2006-10-14') - 1) * 12 +
(strftime('%m', 'now') +
(12 - strftime('%m', '2006-10-14'))) - 1
else
(strftime('%Y', 'now') - strftime('%Y', '2006-10-14') - 1) * 12 +
(strftime('%m', 'now') + (12 - strftime('%m', '2006-10-14')))
end
end

You have an extra closing bracket in the line above.
(strftime('%m', 'now') - strftime('%m', '2006-10-14'))

Try this instead, I find the extra indentation makes it easier to see what
you are doing.
