Quicken 2004 for investing

I use Quicken 2004 for managing investments by creating a security list. I use the Enter Transaction dialogue to update transactions. The security names in my Security List show in the Security Name field all except one. I can't understand why this one security name doesn't display so I can choose transactions for that security. Appreciate any help on how to resolve this missing security name.

 

What security?

 

Fidelity Spartan 500 Index Fund. I use the name Spartan 500 and the symbol FSMKX.

 

Found the cause. The fund must be either a stock fund or mutual fund. I had set it up as an Market Index type.
