    \$\begingroup\$ Begin by fixing your errors (470 pF -> 470p, 3.3 mu -> 3.3m) and by connecting the negatives of V1 and V2 to ground. \$\endgroup\$

\$\begingroup\$
  1. Your capacitor values are incorrectly specified (you need to write 470p and 3.3u rather than 470 pf and 3.3 mu)
  2. The negative terminals of V1 and V2 aren't connected to anything.

\$\begingroup\$

Your capacitor values are malformed: You have to remove the space in "470 pF" (otherwise it gets interpreted as multiple parameters, and ideally you just write "470p"), and use "µ" or "u" instead of "mu".
