My dB has a column name called price and the value of currency how do you convert it to currency?

i have this in place
If Request.Form("price") = vbNullString Then
strSQL = strSQL & "0,"
Else
strSQL = strSQL & ccur(Request.Form("price")) & ","
End If
and i get this error
Disallowed implicit conversion from data type varchar to data type money, table 'ShaganappiTest.dbo.used_cars', column 'Price'. Use the CONVERT function to run this query.
I assums i Have to do something with the 0 but what....
