Smart Part Number based on combined lists

Hello,

lets say i have a template card with inputs as following

- Material

- Thickness

- Coating

i created 3 lists for each variable and used it in 3 Combobox Droplist

as per the image, i have 4 results for each material, total is 12 output, each output represented by specific code.

my question is, how i could get the output based on the selections of 3 inputs to be used in part numbering ?

i believe i could get it by editbox with input formula, but i didn't know what is exact string

anyone can help in this ?
