Try using the debugger, to see what value ENTRADA has. Or check your code, to see whether you don't assign a value to it.

ENTRADA = CreateObject("cMainForm") && Type = "O"
ENTRADA = .T. && Now, Type = "L" (logical)

Or perhaps the variable ENTRADA gets out of scope. Is it a public variable? Do you hide it somewhere with LOCAL or PRIVATE?
