I think there is a problem in field type in Days because the default is a
string so days have a string value, you are multiplying string with an
integer in the computed field.
# 1
db.define_table('ClientDetails',
Field('CheckIn', 'date', label=SPAN('Check-In Date',
_style="font-weight:
bold;")),
Field('CheckOut', 'date', label=SPAN('Check-Out Date',
_style="font-weight: bold;")),
Field('Days', compute=lambda r: (r['CheckOut']-r['CheckIn'
]).days),
Field('Amount', compute=lambda r: int(r['Days'])*int(r[
'Number_of_Guests'])*650))
# 2
db.define_table('ClientDetails',
Field('CheckIn', 'date', label=SPAN('Check-In Date',
_style="font-weight:
bold;")),
Field('CheckOut', 'date', label=SPAN('Check-Out Date',
_style="font-weight: bold;")),
Field('Days', compute=lambda r: (r['CheckOut']-r['CheckIn'
]).days),
Field('Amount', compute=lambda r: ((r['CheckOut']-r[
'CheckIn']).days)*int(r['Number_of_Guests'])*650))
Let me know this will work for you.
Thanks
