Line 23 looks suspicious to me, especially because n1 and n3 are ints which you
don't have to quote like '42' etc. in SQL.

That one should be easy; print out that 'str' String containing your SQL query and
check what is wrong with it. I still suspect those quotes around those numbers.
Also check out the SQL dialect for Microsft Access and see what the syntax
for the update statement is supposed to be.
