[Gretl-users] "If-Else" syntax help

Dear Gretl community, I'm not a good "if-else" user so I need a little help. What's wrong with the following code? <hansl> open australia.gdt series E_hp = E - hpfilt(E, 1600) if E > E_hp series E_reg1 = E series PAUreg1 = PAU series PUSreg1 = PUS else series E_reg1 = NA series PAUreg1 = NA series PUSreg1 = NA endif <hansl> When I execute it I get the messages: "error evaluating 'if'" "Error executing script: halting". Best regards, Henrique Andrade
