Narrative:

After we got the takeoff data; I put zero fuel weight (ZFW) on performance init 3/3 in 4L. I noticed we have to move 3 passengers from C to a. I got distracted after we got the new data. I forgot to confirm the ZFW in the performance page. I thought I confirmed it but actually; I didn't. I put the speed; temperature; ecs and flex. Then we started taxing. When we reached the end of the runway; I noticed on top of the speed tap FMS speed showing 3 dashes. I checked the takeoff page and saw all the speed and flap showing correct. I thought it's a glitch. I put the speed to manual speed and did the takeoff from runaway 09. After takeoff; we flew tower assigned runway heading. During climb out; got a frequency change to center and got direct to initial fix. Did a left turn and started to climb. During climb; we got caution terrain aural message. Hence we made a left turn and avoid the weather balloon. After that; we went direct to initial fix. Mean time going through the performance init page; I noticed I forgot to confirm the ZFW. At that point; I confirmed and fix the FMS speed problem and continued the flight. [My] suggestion [is to] avoid getting distracted while putting the numbers and double-check the numbers after we did.
