Data Conversion Error - How to Fix this?

Hi All,

I have a Excel source and a OLEDB destination. I am trying to upload data to a table. I get the following error.

[Excel Source [306]] Error: There was an error with output column "Open" (346) on output "Excel Source Output" (314). The column status returned was: "The value could not be converted because of a potential loss of data.".

When I check on the Excel source advance editor input and output properties section the open column has a double-precision float [DT_R8] for the external columns and output columns. 

Still I get the above error. Some sample data for open column is

20.38,blankcolumn,  6.6,6.5.

Any idea why this is happening?

Thanks

Lucki
