HELP>>HELP>>Using an Index for an MSSQL database

I have a MSSQL database residing on a server. My TDatabase
component connects to it just fine. However, when I use a
TTable to get one table from the database, and then use FindKey
to access a particular record, I get and error which states that
no index is active. The MSSQL database has an index on that
table, I've tried IndexName, IndexFieldNames, etc. What am I
doing wrong?????Please help.....

Thanks, Brian
