Invalid variable and operator

[Paul Elguezabal]

Hi, I am having trouble with this data set. Any time I run a regression it shows this invalid 'variable' r(198) but also it is not recognizing i. as a valid operator. I am able to create histograms, correlation tables, and many other opeations with these varaibels but I cannot do regressions. What is going on?

r(198);

i: operator invalid

Stata is confused. The = sign does not belong in your syntax for what you want. Perhaps you are thinking in terms of syntax that works somewhere else.

What a stupid mistake. Shame on me. Thank you for your time
