Hi Ashkay,

Yes, nesting grave accents is tricky. You probably need to break things
up into a few steps

I would define a symbol first for  "variable" first and then define your
new anomaly variable. I presume "variable" is a string variable.

def symbol var `variable[d=2]`
let/units="`($var),RETURN=units`"/TITLE="`anomaly_title`"/`anomaly_var`=($var)_anomaly

Cheers,
Russ
