Error in Code for Math Expression

Hi,

I'm trying to render maths like this.

Code: Select all

$\text{SPRT}{}_{j=1\sim4}=\sum\limits_{s=i}^{k}\ln\left(\frac{\fint_{j}\left(\chi_{s}\right)}{\fint_{0}\left(\chi_{s}\right)}\right)$
I cannot find the error. Compilation problem is:

Code: Select all

! Undefined control sequence.
Any help is appreciated! :?:
