st: RE: assertion is false error: mvencode

["O'Keeffe, Linda" <L.OKeeffe@ucc.ie>]

Hi

I am using Penn State University doLCA command. I keep getting an error after some of the code has run saying 

"389 contradictions in 708 observations"

assertion if false 

r (9)


r (9) error code says "   error . . . . . . . . . . . . . . . . . . . . . . . . .  Return code 9

        assertion is false;

        no action taken;

        Return code and message from assert when the assertion is false;

        see [D] assert.

        Or, you were using mvencode and requested Stata change `.' to #

        in the specified varlist, but # already existed in the varlist,

        so Stata refused; see [D] mvencode.

I assume this is a problem with my data but I don't know what. Any assistance would be most greatly appreciated!
Linda
