Compilation error - undefined operation in rootsize mixin

[ngo6012]

Hello! I'm setting up Sassline in my project and am getting an error when I compile.

My error is:

File "assets\scss\vendor\sassline-master\sassline-base_variables.scss" changed.
Running "sass:dist" (sass) task
Error: Undefined operation: ""(min-width: 90.0625em) and (max-width: 120em)"/16 times 1em".
on line 52 of assets/scss/vendor/sassline-master/sassline-base/_mixins.scss, in `rootsize'

My variables are set as follows:

$breakpoints: (
xsm: 320,
sm: 480,
smd: 640,
md: 785,
mdlg: 900,
lg: 965,
lgr: 1080,
xlg: 1200,
wd: 1280
) !default;

$rootsizes: (
rootsize-0: 12, // 24px line-height body text
rootsize-1: 14, // 28px line-height body text
rootsize-2: 15, // 30px line-height body text
rootsize-3: 17, // 34px line-height body text
rootsize-4: 19 // 38px line-height body text
) !default;

Many thanks in advance for any guidance!

Hi, i believe you need a rootsize for every breakpoint. So, you need up to rootsize-8 to match your number of breakpoints.
