How dangerous are duplicate page titles

[SimonDixon]

We ran a SEO crawl and on our report it flag up duplicate pages titles, we investigate further and found that these were page titles from the same product line that had more than one page, e.g 1-50 (products) 51-100 (products) with a next button to move to the following 50 products.

These where flagged as duplicate page titles ".../range-1/page-1" and ".../range-1/page-2"  These titles are obviously being read as duplicates but because they are the same range we do not know what the best course of action is.  We want to know how detrimental these page titles will be to our SEO if at all.

If anyone could shed some light on this issue it would be a massive help.

Thanks
