As you see we added a white box for the result and put a place holder text inside. And we had to do code to dynamically look for what controls FileMaker places there and measure their size to place our box between controls on the left and controls on the right. Let us know if we got it wrong in your FileMaker version or language.
Check 11.1pr4 to try this feature. Looks like the features work even in lots of older FileMaker versions down to version 14.
