Hello everyone,

I am writing a master thesis and try to construct a SEM with Mplus. Without interaction terms, everythin works just fine. But as soon as I want to include interaction terms, I got error messages. I am very puzzeld now as I really tried everything and I really don't see where the error comes from. I would be very thankful if someone could help me.

Maybe someone could tell me what newbies are doing wrong usually when constructing interaction terms. The error messages are:

*** ERROR in DEFINE command
Error in assignment statement for USEVARIABLES

As I said, the complete data set works well without the interaction terms. in the define statement I wrote:

DEFINE:
INT_1=(IMA_2*MAGE);
INT_2=(IMA_5*MAGE);
INT_3=(IMA_10*MAGE);

And of course I listed the variables, from which the interactions should be created in the variables part and in the usevariables part I listed the interaction terms...

Maybe someone could tell me the reason for the error messages? Thank you very much!!
