I'm trying to make a bode plot, what am I doing wrong? and how should I do?
Its hard to impossible to debug a picture. So you should provide your Prime sheet.
Chances are that you had defined omega somewhere above the calculations you show.
So you may decide to redefine omega as a range similar to what Fred had shown or use a differently named variable for plotting.
Luc's guess was correct - you wrote a function call C1(rc+R1) instead of a multiplication C1*(rc+R1).
But there is a second error, too, which will make your phase plot fail. You typed square brackets  instead of parentheses (). Square brackets mean that you create a matrix/vector!
Correcting these two errors, maybe adding a range variable to select the frequency range for plotting and use a log scale should give you the plots you are looking for.
BTW, you can create a true omega if you type a w and then Type Ctrl G.
rc * C1 is a time constant, i.e. it has the dimension of a time (second). The complex variable s can be defined as a complex angular frequency (pulsation) with dimension second ^ (- 1).
So s * rc * C1 is dimensionless. This must also apply to the denominator. It does not have a physical meaning to add a resistance to a capacity ... so the denominator must be (C1 * (rc + R1) + C2 * R1) s + C1 * C2 * rc * R1 * (s ^ 2).
Please attach your worksheet, not just a picture!
You've probably typed C1(rc+R1) instead of C1*(rc+R1). Now Prime tries to evaluate the function C1.
Or did you define w somwhere upwards?
