Tax total breakup in A/R Invoice udf

Question

Hello all,
I am trying to print the tax total in the PLD of the Tax Invoice. I have created udf in the invoice and added the following code as formatted search.
SELECT T1.[Taxsum] FROM OINV T0 inner join INV4 T1
WHERE T0.[Docentry] = T1.[Docentry] and T1.[staTtype] = -90
and T0.[Docnum] = $[OINV.DocNum]
The above code is for VAT. this returns correct value for 1 item, but when there r more than 1 items, it gives me a choice to select the vat amount for the individual items. I need to sum up all the vat amounts and enter the summed amount into the field. How do I use the Sum function to correctly reflect the total vat amount of the whole invoice instead of giving me individual amounts?
I use a similar code for the tax percent. but that has the same problem as well.

Hi Gordon,
I was going through previous threads and I came up with a query suggested by K Shreyas
Formula for tax break up in PLD documents
Suppose you want the total Excise Amount for the document in A/R Invoice
attach this query as a formatted search
SELECT sum(taxsum), t0.docnum as "Doc Num" FROM OINV T0, INV4 T1
WHERE T0.Docentry = T1.Docentry and T1.statype =-90
and t0.docnum =$http://OINV.DocNum group by t0.docnum
I modified the above query as in the first post to give me a single value successfully, but when I try the sum function it doesn't work. I thought I was not using the correct syntax and hence my question. The client needs the total sum of the Taxsum column for each of the percentages to be mentioned in the invoice generated.
