Accidentally selecting 300 pages

[maxthebear]

I have an Excel 2007 file with a number of tabs, about 15. All has worked well until today. All of a sudden I want to print one page and the preview shows I have 300 pages selected!!!!

I cleared all print ranges,even on hidden files. No luck.....

I only selected one page. it tells me my print margins are off but it will not let me get to any changes in page setup......

I tried printing a few of them and I just get the top few rows of each page.

Any ideas to fix this are appreciated...
