The error statement is telling you need to change the line "estimates
hold..." to "_estimates hold..."
But there is a much more fundamental problem. -bpagen- is the Breusch-Pagan
(1979) Lagrange multiplier test for heteroskedasticity, not the
Breusch-Pagan (1980) LM test for cross-sectional correlation in fixed
effects model
You should take a look at -xttest2-.
Hope this helps,
