Hello!
Yes, you figured it out! That’s exactly what those red squares mean – the fields are too close to one another. As you saw, separate them a bit more and the red squares will disappear.
As for viewing the print preview mode – that’s really designed more for the view that you’d see if you were to print directly from Method Report Designer, which is possible; however, in most instances, you’d access a report from within Method via the Report object which then generates the report template that you already created.
The HTML mode is designed for optimizing the view of the report in web-based format. So, if you’re designing a report that is going to be viewed on the web, you’d want to view the HTML mode so you can get a better idea as to how it will look when it’s finished.
It’s probably a good thing to note that the preview modes – both print preview AND HTML preview are meant to be just glimpses of the final report and may have slight variances from the finished product. You can always go back in and make the minor cosmetic adjustments easily to the template.
Hope this helps!
