## Calculation Problem

Level 2

How to create a formula to calculate integers and dates using formcalc within LiveCylce ? (i.e. Sep 1, 2015 + 1 + 3= Sep 5, 2015)

if (Start.rawValue==null) then

\$.rawValue = ""

else

Num2Date(Date2Num(Start.formattedValue, DateFmt(2))  + stop + ext, DateFmt(2))

endif

2 date fields named Start and Comp

2 numeric fields:  stop and ext

The script is FormCalc on the calculate event of the date field named Comp

use a date field named StartDate.

Add a text field and add a script written in FormCalc utilizing the calculate function:

if (StartDate.rawValue==null) then
\$.rawValue = ""
else
Num2Date(Date2Num(StartDate.formattedValue, DateFmt(2))  + 1, DateFmt(2))
endif

change the + 1 to increase the number of days calculating from the start date

Date formats can be changed by using DateFMT(1) or DateFMT(2) or DateFMT(3)

or you can create a custom format

The problem I am having is that I want the "Start Date" field and the "+1" "+2" "+3" etc. fields to be input at random.  Each one of the integer fields would be a separate field that the user would enter a number into and it may not be the same number every time.  It may be 1 or it may be 28.  How do I get the form to auto calculate the "start date" plus the two other fields that are changed by the user (ie. "stop days" and "extension days") to get an "Estimated Completion Date"?

Awesome! I tried it and everything worked perfect!  I have another equation that I need help with that is very similar to the previous one... I want to take a "Days Allowed" - (End Date - Start Date)= "Days Remaining" (I need it to be an integer, not a date).  Thank you so much for your help!

same as above except a new field (call it whatever you want)

Add this script to the new field using "calculate":

if (Date2Num(EndDate, "YYYY-MM-DD") and Date2Num(StartDate, "YYYY-MM-DD")) then

if (Date2Num(EndDate, "YYYY-MM-DD") &lt; Date2Num(StartDate, "YYYY-MM-DD")) then

xfa.host.messageBox("The second date is earlier then the first date.\u000aThe date fields will reset.", "Information", 3, 1)

StartDate = null

EndDate = null

\$ = null

xfa.host.setFocus("StartDate")

else

\$ = Date2Num(EndDate, "YYYY-MM-DD") - Date2Num(StartDate, "YYYY-MM-DD") + 1

endif

else

\$ = null

endif

When you say "same as above" do you mean I can just leave the previous equation I entered and not change anything as far as the field and coding? Also, when I input the new equation you gave me in numeric field called "Days Remaining" it gives me a syntax error for this line: "if (Date2Num(DateField19, "YYYY-MM-DD") &lt; Date2Num(DateField3, "YYYY-MM-DD")) then" saying "syntax error near token "lt""

Level 6

You can leave leave all alone and in the new field add the script.

Syntax:  Without seeing the form structure it's difficult to diagnose but try changing the date field names to StartDate and EndDate

Level 2

it also gives me a syntax error for this line: "  xfa.host.messageBox("The second date is earlier then the first date.\u000aThe date fields will reset.", "Information", 3, 1) " saying there is an error for "xfa"

This the problem I am still having.

Level 2

I clicked "right answer" but I am still having issues.

Level 6

Can you send me the form?

Level 2

Yes sir. It has been sent.
