if – then

dear support,

i wonder if it is possible to create a “if – then” function.

so i have a) a toggle for lets say 3 values
and next b) 3 checkboxes for options which should be added to a)

so when i choose a) the value 2 then b) will add another value (price) than compared if i choose a) value 1 or 3.

i hope i explained it good enough ??

thanks for your help and support! kai
