The followings are the input and output I have. The program keeps saying that "CINDICATORS" option is unknown.... What's wrong with my syntax?

Hi, I have an latent class model with 7 indicators, a continuous covariate and binary group. I am unsure how to construct the syntax to hold item response probabilties invariant over the groups, but leave the other parameters (latent statuses and covariate effects) to vary between the genders. Can you advise as to what the syntax should look like? Cheers, Oxnard
A week or so ago, somebody asked about using TECH11 (LMR) and TECH14 (BLRT) to determine the number of latent classes. They were concerned about needing to have their largest class last. An Mplus Web Note No. 14 is now available and will shortly be posted that gives a detailed description of how to use these methods. The note describes the K-1STARTS and LRTSTARTS options that go with TECH11 and TECH14. It points out that re-ordering the classes to have the largest class last is not necessary. Avoiding local optima by replication of the best loglikelihood value is discussed. The note also shows the value of the OPTSEED option. A 3-step strategy is presented for doing the analyses successfully and with as little computational time as possible.
