How do I handle a stock basis of zero and a loss in the s corp

2008 was the first year as an s corp. There was a stock basis of $1000 then our cpa had a loan made to the s-corp for $1635. I had a loss of $3347 and with the value of the stock figured in I had a carry over of $843 Our cpa put my stock basis at the end of the year at a zero. Is that normal practice?
Well for 2009 the company had a loss again and I never bought more shares in to company. So on the schedual K-1 there is a loss of $2297 and she had a basis carry over of $843. Since my stock basis is at zero how do I figure my stock basis. As far as I can figure out I have no stock basis plus I have a loan that the company hasn't paid back to me yet. (I should have paid closer attention and asked more questions. Just didn't know the questions to ask. Learning now) So for my schedule E part II section 28 do I show a zero or can I add the two sums ($2297 and $843) and put this down as a loss on the form. I hope this makes a little sense. Why did she put the stock basis at a zero for the end of the year? Thanks for any help.
