<prompt> Human: I am a first time investor and panicking. I opened an account with Vanguard and wanted to invest in their Vanguard 500 Index Fund Admiral Shares VFIAX.However I got a prospectus and it says I have Vanguard Federal Money Market Fund Investor Shares VMFXX. I have no idea what this means. Did I invest in the wrong thing? Why doesnt it say I have VFIAX? Or is this the first step I need to go through in order to buy into the Admiral Shares?I am trying to call them but am currently overseas. I am really sorry if this isnt the right place to post, but since I have to wait a few days for them to reply to me by email, I wanted to try and brace myself for the worst.EDIT: Thank you for your quick responses and patience with me! I am now pretty embarrassed and next time need to do much more research before I invest like this. Sorry I panicked and for the vulgar language. I dont know how to change the titled to take out the f-bomb :  <response>: The money market is where your money is held before you invest it. Everyone gets the money market prospectus. They are required to send you all this paperwork because of the lawyers.Check to make sure your money actually got invested in something.
