The answer appears to lie in the hierarchy and naming. All forms, pages, subforms, etc. have to be named exactly the same and have the same hierarchical flow for the floating text fields to bind properly to imported data. This kind of blows for my purposes, as "form2" had my text fields spread across multiple pages and multiple subforms. Naming all the subforms the same as the subform in "form1" made the first one work, but none of the subsequent.
If anyone has any alternative thoughts, I'd appreciate it. My workaround is to put ALL of my text fields in form1 on the same level, and then call them out one by one in the scripting to make the ones I want visible or hidden. Wrapping them in a subform just causes too much trouble down the line. Ugly, but functional.
Thanks,
