Importing prices and its stripping out a comma

SOLVED

Hi,

We are going through a price increase and for some reason when I try and import the prices some of them fail with a "Price entered for price band is linked to standard price. Price ignored"

If I look at the Error log I can see that its erroring because its stripping out a comma between the part number and the standard price, at least that's how it looks on the report. 

What does the "Price entered for price band is linked to standard price" actually mean? 

Cheers.
