SetBodyPageUsage isn't working?

This is for Digital Storefront.

The job consists of two pages, a pick list in the 'HTML Form' returns either the value 'left' or 'right' based on choice.

The rule (onrecordstart) defined as a 'callback' looks like this:

if (Field("arrow") == "right")

{

FusionPro.Composition.SetBodyPageUsage("right", true);

FusionPro.Composition.SetBodyPageUsage("left", false);

}

else

{

FusionPro.Composition.SetBodyPageUsage("right", false);

FusionPro.Composition.SetBodyPageUsage("left", true);

}

I've set the second page as 'unused' under page usage, and i've named the pages 'right' and 'left' also under page usage. (1 is right and 2 is left).

It returns page 2 (left) no matter what you choose in the pick list (arrow).

What have I done wrong?

Add this line to the rule:

Print(Field("arrow"));

And look in the log (.msg) file to see what it prints. It might not have the value you expect at composition time. Also, double-check the names of your pages.

Might be me that's dense, but I get a 'ReferenceError: field is not defined' on that Print line of code you gave me.

I've double checked that the fieldname is indeed correct.

That makes no sense. Did you copy-and-paste the code exactly from my post? Are you sure that "Field" has a capital "F"?

ehem ... I did not copy+paste because I translated some of the content. So i did forget the capital F.

Not used to writing code myself, mostly copy+paste and editing.

Thanks again, Dan, you da man.
