Change Mergedate in Macropod's example to Date then the date + 3 is
calculated from the system date rather than the merge date.

Hi TotallyConfused,

At the start of this thread you said you wanted help to "revise this merge field to add 3 business working days". Now you say "the
due date is not a merge field".

If the date you want the calculation to be based on isn't from your mailmerge data source, then I suggest you use the example found
under 'Calculate a day, date, month and year, using n days delay' and modify it to suit. As coded, the field uses the current system
date and looks like:

{QUOTE
{SET Delay 14}
{SET a{=INT((14-{DATE \@ M})/12)}}
{SET b{={DATE \@ yyyy}+4800-a}}
{SET c{={DATE \@ M}+12*a-3}}
{SET d{DATE \@ d}}
{SET jd{=d+INT((153*c+2)/5)+365*b+INT(b/4)-INT(b/100)+INT(b/400)-32045+Delay}}
{SET e{=INT((4*(jd+32044)+3)/146097)}}
{SET f{=jd+32044-INT(146097*e/4)}}
{SET g{=INT((4*f+3)/1461)}}
{SET h{=f-INT(1461*g/4)}}
{SET i{=INT((5*h+2)/153)}}
{SET dd{=h-INT((153*i+2)/5)+1}}
{SET mm{=i+3-12*INT(i/10)}}
{SET yy{=100*e+g-4800+INT(i/10)}}
"{dd}-{mm}-{yy}" \@ "dddd, d MMMM yyyy"}

First off, make the same changes that I outlined in my previous post. This will give you:

{QUOTE
{SET Delay 3}
{SET a{=INT((14-{DATE \@ M})/12)}}
{SET b{={DATE \@ yyyy}+4800-a}}
{SET c{={DATE \@ M}+12*a-3}}
{SET d{DATE \@ d}}
{SET jd{=d+INT((153*c+2)/5)+365*b+INT(b/4)-INT(b/100)+INT(b/400)-32045+Delay}}
{SET jd{=jd+(MOD(jd,7)>4)*(7-MOD(jd,7))}}
{SET e{=INT((4*(jd+32044)+3)/146097)}}
{SET f{=jd+32044-INT(146097*e/4)}}
{SET g{=INT((4*f+3)/1461)}}
{SET h{=f-INT(1461*g/4)}}
{SET i{=INT((5*h+2)/153)}}
{SET dd{=h-INT((153*i+2)/5)+1}}
{SET mm{=i+3-12*INT(i/10)}}
{SET yy{=100*e+g-4800+INT(i/10)}}
"{dd}-{mm}-{yy}" \@ "dddd, d MMMM yyyy"}

As per your latest post, this should give you what you say you want, but anything based on a plain DATE field is liable to change
the calculated date every time the document is opened. I suggest you think carefully whether that it appropriate - including for the
DATE field you're already inserting. If you don't want the field changing the results every time you open the document, change all
'DATE' instances to one of 'CREATEDATE', 'SAVEDATE' or 'PRINTDATE', depending on what you want to achieve.

If, instead of using the system date with a 'DATE', 'CREATEDATE', 'SAVEDATE' or 'PRINTDATE' field, you want to be prompted for the
starting date:
. change all 'DATE' instances to 'StartDate'
. add a new second line coded as: {ASK StartDate "Please input the start date"}
This will give you a field coded as:

{QUOTE
{ASK StartDate "Please input the start date"}
{SET Delay 3}
{SET a{=INT((14-{StartDate \@ M})/12)}}
{SET b{={StartDate \@ yyyy}+4800-a}}
{SET c{={StartDate \@ M}+12*a-3}}
{SET d{StartDate \@ d}}
{SET jd{=d+INT((153*c+2)/5)+365*b+INT(b/4)-INT(b/100)+INT(b/400)-32045+Delay}}
{SET jd{=jd+(MOD(jd,7)>4)*(7-MOD(jd,7))}}
{SET e{=INT((4*(jd+32044)+3)/146097)}}
{SET f{=jd+32044-INT(146097*e/4)}}
{SET g{=INT((4*f+3)/1461)}}
{SET h{=f-INT(1461*g/4)}}
{SET i{=INT((5*h+2)/153)}}
{SET dd{=h-INT((153*i+2)/5)+1}}
{SET mm{=i+3-12*INT(i/10)}}
{SET yy{=100*e+g-4800+INT(i/10)}}
"{dd}-{mm}-{yy}" \@ "dddd, d MMMM yyyy"}

The example under 'Interactively Calculate A Past Or Future Date' in the tutorial document has a more elaborate version of this.

Finally, if you want to be prompted as per the last field, but only once per mailmerge, add a '\o' switch to the ASK field (ie {ASK
StartDate "Please input the start date" \o}).

Cheers
