I know InDesign isn't a "web app" but I've received great information here in the past so I figure I try here.

Trying to make PDF download for my site.

It's an odd problem. I have a spread, left side has a rectangle going from the top to the bottom. Then I have another rectangle going across both pages of the spreads. The first rectangle should be on top of the bigger one going across. However when I go to export it as a PDF, the larger one going across always shows up above the the first one. However, if I horizontally shrink the rectangle so it only shows on the left page, and export as a PDF, the problem is resolved. But for some reason the bigger rectangle always shows above the first one when exporting a PDF if it spans both pages of the spread.

I hope that makes sense as it is a weird issue. Basically imagine a lower case "T" on it's side, and if the longer side is across the entire spread it's above the smaller shape regardless of the arrangement before exporting to a PDF.

Thanks in advance for any help
