simple if-statement

Hi, I want to create a new field called "total_Qty_sold", that uses an If-statement, that sums the field called "TOTAL_SHIPPED_QTY",  but if the shipped qty is zero ("0"), then it should be replaced by the field called "ORDER_QTY", only if the field called "STATUS" is like "R".

 Please give me the complete SQL for me to copy and paste, based on the attached code snippet.
 thank you very much
SELECT [1].PART_ID, [1].STATUS, [1].TOTAL_SHIPPED_QTY, [1].ORDER_QTY
FROM qryLUPSTCtotalSls_01 AS 1
WHERE ((([1].TOTAL_SHIPPED_QTY)>0)) OR ((([1].STATUS)="R") AND (([1].TOTAL_SHIPPED_QTY)=0));

Something like this may be:

SELECT [1].PART_ID, [1].STATUS, [1].TOTAL_SHIPPED_QTY, [1].ORDER_QTY,SUM(IIF([1].TOTAL_SHIPPED_QTY = 0, IIF([1].STATUS="R", [1].ORDER_QTY,0), [1].TOTAL_SHIPPED_QTY))
FROM qryLUPSTCtotalSls_01 AS 1
WHERE ((([1].TOTAL_SHIPPED_QTY)>0)) OR ((([1].STATUS)="R") AND (([1].TOTAL_SHIPPED_QTY)=0));

This uses CASE instead of IIF

SELECT [1].PART_ID, [1].STATUS,
      [1].TOTAL_SHIPPED_QTY,
      [1].ORDER_QTY,
      total_Qty_sold = CASE WHEN [1].TOTAL_SHIPPED_QTY = 0 AND [1].STATUS = 'R' THEN [1].ORDER_QTY
                              ELSE [1].TOTAL_SHIPPED_QTY
                              END
FROM qryLUPSTCtotalSls_01 AS 1
WHERE ((([1].TOTAL_SHIPPED_QTY)>0)) OR ((([1].STATUS)="R") AND (([1].TOTAL_SHIPPED_QTY)=0))

Correction to my syntax, took the sum function out since you do not need it:

SELECT [1].PART_ID, [1].STATUS, [1].TOTAL_SHIPPED_QTY, [1].ORDER_QTY,IIF([1].TOTAL_SHIPPED_QTY = 0, IIF([1].STATUS="R", [1].ORDER_QTY,0), [1].TOTAL_SHIPPED_QTY)
FROM qryLUPSTCtotalSls_01 AS 1
WHERE ((([1].TOTAL_SHIPPED_QTY)>0)) OR ((([1].STATUS)="R") AND (([1].TOTAL_SHIPPED_QTY)=0));

I dont think that it is summing correctly, bec I am getting mutliple records for the same customer_ID, with diffrent figures . please advise

SELECT DISTINCT [1].PART_ID, [1].CUSTOMER_ID, IIf([1].[TOTAL_SHIPPED_QTY]=0,IIf([1].[STATUS]="R",[1].[ORDER_QTY],0),[1].[TOTAL_SHIPPED_QTY]) AS total_Qty_sold, [1].TOTAL_SHIPPED_QTY, [1].ORDER_QTY
