You're welcome!
I'm not familiar with PlanMaker. But I know that drive.google.com won't support the number of pages necessary to make the spreadsheet work.
Here's what I suggest you do:
First, try opening it without using read only mode. "Read-only" mode prevents you from being able to make any changes.
Then, if this doesn't help, my suggestion is that you download OpenOffice
(http://www.openoffice.org/). It's a free office suite that will reliably let you work with spreadsheets. You should be able to successfully use the spreadsheet with this program.
