parameter query in MDB

I have this query (qryZipLike) in an MDB file. It accesses a function
geo_distance() and requires input parms for the three parameters.

SELECT tblPrimary.Zip, tblPrimary.State, tblPrimary.City,
geo_distance([@dotnet.itags.org.LAT1],[@dotnet.itags.org.LON1],tblPrimary.Lat,tblPrimary.Lon) AS dist1
FROM tblPrimary
WHERE Zip Like [@dotnet.itags.org.P1];

I am trying to access this query from C# in asp.net using ado.net. I am
really not sure how to do so, but have tried the following code.

OleDbCommand sql1 = new OleDbCommand("qryLikeZip", oleDbConnection1);
theSQL = "SELECT City,Zip,dist1 FROM qryZipLike";

sql1.CommandText = theSQL;
OleDbParameter myparm;

myparm = sql1.Parameters.Add(new
OleDbParameter("@dotnet.itags.org.LAT1",OleDbType.Double,8));
myparm.Direction = System.Data.ParameterDirection.Input;
myparm.Value = lat1;

myparm = sql1.Parameters.Add(new
OleDbParameter("@dotnet.itags.org.LON1",OleDbType.Double,8));
myparm.Direction = System.Data.ParameterDirection.Input;
myparm.Value = long1;

myparm = sql1.Parameters.Add(new OleDbParameter("@dotnet.itags.org.P1",OleDbType.VarChar,4));
myparm.Direction = System.Data.ParameterDirection.Input;
myparm.Value = "030*";

dr = sql1.ExecuteReader();

I get this error at the ExecuteReader call...

Undefined function 'geo_distance' in expression

Can anyone help me with this?Let the microsoft access code generator write the code for you.
