For "Borrower 1 Amount":

if (event.value && event.value!=this.getField("Borrower 2 Amount Re-enter").valueAsString) app.alert("Error! This value must match that of \"Borrower 2 Amount Re-enter\".");

For "Borrower 2 Amount Re-enter":

if (event.value && event.value!=this.getField("Borrower 1 Amount").valueAsString) app.alert("Error! This value must match that of \"Borrower 1 Amount\".");

You might want to add an additional check to see if the other field value you're comparing event.value to isn't blank. I'd find it annoying and probably confusing to get that error message in such cases, at least for the first field.

You can use this code as the custom validation script of field B:

if (event.value && event.value!=this.getField("A").valueAsString) app.alert("Error! This value must match that of field A.");

You should also enter the same thing (adjust the field names, of course) under field A, in case they change it after having changed B.

ok - so if my fields are called the following, what would the custom validation script say, specifically?

  • "Borrower 1 Amount" (aka Field A)
  • "Borrower 2 Amount Re-enter" (aka Field B)

Thanks in advance.

    An important point is that you do not use Java, you use JavaScript (one word, never shortened to Java). The reason to point this out is, if you go searching the web for advice on Java, you will get information that is useless to you. Must be JavaScript; it must be Acrobat JavaScript, which is a special type.
