Dear helper.

How would I do this?

I have 2 tables.

Table 1,
Service Type A Service Type B Service Type C
boxtype |zoneA|zoneB|zoneC |zoneA|zoneB|zoneC |zoneA|zoneB|zoneC
A 10 20 30 15 25 35 20 30 70


Table 2,

Province | Zone
ABC A
ABD B
ABE A
ABF C

Now my report is.

I can get the boxtype, Service Type, Province.

Example

if I get,
A (boxsize) | Service Type (B) | ABF (province - zone C)

if all the criteria are match, then show the numbers (70)

How do I create functions for this, pleae help.

Thx,
