I would like to preform the following calculation but am not sure of the syntax
If ( DateA is greater than or equal to ( DateB less 14 days ) ; 1 ; 10 )
I am getting stuck DateB - the 14 days
Thanks in advance,
If ( DateA >= ( DateB - 14 ) ; 1 ; 10 )
Or am I missing something in your question?
I think the problem is I am missing something,
Would (DateB - 14) subtract 14 days in a number calculation?
This calculation requires a bolean result 1 = true 0 and others = False
Jason, (DateB - 14) would indeed return a number but
if (dateA >= (DateB - 14);1;10) the DateA >= (DateB -14) that should return a true or false value (1 or 0) do you have Filemaker Pro advanced? You can use the data viewer to see what your results are while you are trying to build the correct calculation.
What exactly are you trying to accomplish with your calculation? In words?
It is a filter for a portal
Only show dates that are 14 days before DateA
I think I have worked around it by using a separate calculation field based on a date calculation and using an IF statement which gives me the boolean result.
Then I pointed the filter to that separate calculation field with again an IF statement
It is working ok, but I am not sure if that was the cleanest way to go about it.
to chime in: your description makes me think that you're working with the data on the backend (the table in the portal). Unless I'm misunderstanding your goal, wouldn't it be easier to define a global calculation on the front-end, like myGlobal = [ dateA - 14 ], and use this as a match field for dateA in your relationship?
This way you could also factor out the parameters and write a calculation like myGlobal = [ myDate +/- myOffset ], where myDate and myOffset are two other globals. This lets you perform all sorts of filtered queries by simpy changing the parameters.

In that case, one of these equations should do the trick.
DateB = DateA - 14 // shows dateB exactly 14 days before dateA
DateB <= DateA - 14 // shows all dateB 14 days or older than dateA
If you provide an IF statement to do this one of the results must be true and the other false. For all practical purposes in Filemaker that is a one or a zero. The IF statement that you provided had two positive results. The answer would be 1 or 10. Both of those numbers evaluate to true.
