Which verb form correctly completes the sentence? él en el mercado ayer. estuve estuviste estuvo estuvimos

What is no tengo ni idea in swedish

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

How will you ask a friend for his phone number
