Error when Importing Sales Orders

SOLVED

Hello All, 

I am trying to import sales orders created from a third party. All works as it should, except when adding a discount to a line item. I get an error that says "ERROR: Line item extended price must be equal to line item unit price times line item order quantity". This is only when applying a discount. I can see in the text file that the math is correct, though it wont import. 

I thought it might be the third party software, so I made an order in Sage, exported it, and tried to import it as is. The orders that do not have any discounts import correctly, though the lines with discounts give the above error. 

Any help would be appreciated! Thanks!
