out or inout argument 1 for routine deed.spallocatedock1 is not a variable

Hi

while executing mysql stored procedures with Vb, the error : 'out or inout argument 1 for routine deed.spallocatedock1 is not a variable ' arise.

I'm using both in and out parameters

Mysql odbc3.51.13 driver is used

What kind of error this is and how to execute stored procedures with out parameters with VB .

Any one give sample code

thanks
