Getting a table to update when a certain option is selected

Hi,

I am relatively new to MySQL so I was hoping that somebody could help me. I am not sure if this is the correct place to put this but I will go ahead anyway.

I am looking for a query that updates another table depending on what opion is selected (Reservation,Appointment, MMC, SYC Appointment, SYC Valuation Form and Not Available). Each of these are worth a different Value (See below)...

Reservation 2
Appointment 2
MMC 1
SYC Appointment 1
SYC Valuation Form 1
Not Available 0

I have used this query:

UPDATE vehicle_collection.ind_summary
JOIN vehicle_collection.form
ON vehicle_collection.ind_summary.TM_ID = vehicle_collection.form.TM_ID
JOIN vehicle_collection.result
ON vehicle_collection.form.Enquiry_Result_ID = vehicle_collection.result.Enquiry_Result_ID
SET ind_summary.Total_Points = ind_summary.Total_Points + vehicle_collection.result.EnquiryValues,
ind_summary.Target_Countdown = ind_summary.Target_Countdown - vehicle_collection.result.EnquiryValues
WHERE vehicle_collection.ind_summary.TM_ID = " 115 " ;

Table 1:
Enquiry_ID|TM_ID| username|Enquiry_Result_ID
1 115 Bob Appointment

Table 2 (Updating)

TM_ID| Total_Points|Target_Countdown|
115 0 100

Once the form is submitted I want it to look like this:-

TM_ID| Total_Points|Target_Countdown|
115 2 98

The issue with this query is for each option, the second table doesn't update untill it has been entered twice??
