Calculate total in repeat region

[Simon Gare]

Hi,

I need to calculate a total based on fields in a repeat region, these values
are stored in an SQL db, all are numeric and written in ASP.

fields are

TOTAL_COST VAT GRANDTOTAL (Page selects records based on
field parameter and displays in a repeat region)


At bottom of page need to show total sum like

TOTAL_COST(sum of above)
VAT(sum of above)
GRANDTOTAL(sum of above)

Thanks in advance
Simon
