How to log airfuel or airfuel volts onlivelink6.5???

[churro]

I got the ngk wideband but i can't log the airfuel, i need to log it on volts or airfuel.

I search and found this formula (v x 1.4) + 9 but as soon as i insert the formula i can't press ok, if i go to the commands - anolog equations and insert the formula it don't work.

How can i log it? here's a pic of where I'm trying to insert the formula.
