I am using Microsoft Word 2002. I copied the following code from
www.addbalance.com (I changed the bookmark name and number of days being
subtracted):

{QUOTE {SET Delay "29"}}{SET "NextPrevMonth" {IF {SALEDATE \@ "MM"} = 1
"12/97" "{ = { SALEDATE \@ "MM"} €“ 1 }/97" }}{SET "DaysInMonth" {IF {
NextPrevMonth \@ "MM"} 2{ = INT(30575*{NextPrevMonth \@ "MM"
}/1000+1/2)-INT(30575*{ ={NextPrevMonth \@ "MM"} €“ 1 }/1000+1/2) }{ IF { =
INT({SALEDATE \@ "yy" }/4) } = { = { SALEDATE \@ "yy"}/4) }"29" "28" } } }{
IF { = {SALEDATE \@ "dd"} €“ {REF Delay \* MERGEFORMAT} } 0{QUOTE {
SALEDATE \@ "MMMM" }" "{ = { SALEDATE \@ "dd" } €“ { REF Delay \* MERGEFORMAT
} \# "0" }", "{ SALEDATE \@ "yyyy"}""}{QUOTE {NextPrevMonth \@ "MMMM" }" "{ =
{ SALEDATE \@ "dd"} €“ ( REF Delay \* MERGEFORMAT} + {DaysInMonth} \# "0"
}", "{ IF { SALEDATE \@ "MM"} 1 { SALEDATE \@ "yyyy"}{ = { SALEDATE \@
"yyyy"} €“ 1 \# "xxxx"}}""}}

When I merge the document with any SALEDATE in March, I receive an error
page that reads "A field calculation error occurred in record 2." When I
close the error page, the document I merged is underneath and the calculation
is correct (unless the SALEDATE is 03/01/2006 then it merges February 0,
2006). I suspect that this has something to do with February only having 28
days. Can anyone tell me what I can do to eliminate the error? Also, as an
added bonus, does anyone know how I can change the code so it won't merge
February 0, 2006?
