Access Import Function Problem

I am trying to import a excel spreadsheet ( 3,000) rows into a access database. It has been working finr for over a year. When I do the import it gives the following message: I have attached part of the excele spread sheet.

'Master 7-20-07$'_ImportErrors Error Field Row
Type Conversion Failure pID 161
Type Conversion Failure pID 162
Type Conversion Failure pID 163
Type Conversion Failure pID 164
Type Conversion Failure pID 165
Type Conversion Failure pID 176
Type Conversion Failure pID 177
Type Conversion Failure pID 180
Type Conversion Failure pID 181
Type Conversion Failure pID 182
Type Conversion Failure pID 183

Type Conversion Failure pID 185
Type Conversion Failure pID 186
Type Conversion Failure pID 187
Type Conversion Failure pID 188
Type Conversion Failure pID 189


Can anyone tell me what is happening. I cannot even paste the spreadsheet into the DB.

Thanks Brian
