hey girls my friend xander needs a someone i would use another app but my phones dead and i was asking if anyone would want to date him hes 13

Stell eine frage: 1. ich hole sie vom bahnhof ab. 2. ich komme nach der schule. 3. in die disko. 4. fahren sie in die 3. etage. 5. im bioladen. 6. wir treffen dort viele leute. 7. im erdgeschoss. 8. ins kaufhaus.

What is wrong in this statement? i have been trying to figure it out for a while, but my notes aren't .

If anyone could teach me some german that would be great, i’m considering taking a german course and wanted to know some basics first. all is appreciated; )
