# Formula Question....

Posted on 2004-09-20

Hi...Have two fields in a form A1 & A2.

both the fields can store multiple values in it. each value is 13 bytes long.

Now I've to put a validation so that no duplicates can be entered.
In A1's input translation I've @Unique(A1)
In A2's input translation I've @Unique(A2)

But i also want to restrict this. If a value in in A1 and the same value is in A2. it should give an error message.

I did put the following in A2's input validation.
@If(a2 = a1;@Failure("cannot enter duplicates");@Success)...

But this works only for some values.(Not sure why... may be becuase A1 and A2 are multi-value fields)

thanks

Let me paste the formula here

List := A1 : A2;
num := "0" : "1" : "2" : "3" : "4" : "5" : "6" : "7" : "8" : "9";
idList := @Subset( num *+ num *+ num; @Elements(List));
tmp1 := @Unique(@Replace(List; List; idList));
tmp2 := @Trim(@Replace(idList; tmp1; ""));
@Replace(tmp2; idList; List);

It returns all the duplicates. I've used  num*+ num*+ num*+ num  as i've more values here.

also, once I save the document it displays me all the duplicates which is great. but i also want this.
once i click ok on the message all the duplicates should be removed from A2.

thanks
Kalios.

Hemanth, I get the list of all the duplicates as return which is great. is it possible to remove duplicates from A2 by using formula or do i have to write a script for that.

a := @Replace(A2;fieldwhereistoredduplicatesfromyourcode;"");
@If(fieldwhereistoredduplicatesfromyourcode = a2; @SetField("a2";a) ;"");
@Command([ViewRefreshFields])
