How to apply the lookup value when formatting the column by JSON

Question

Hi Guys:

  I have a list with lookup value, the lookup source is product name, the lookup value is the column "Product Name:Mic Assembly", and if the Inspection Type is "Mic Assembly", I hope the Workstaion Qty will be "9" as shown in the "Product Name:Mic Assembly" column. 

  But the expression below can't get the value, could you help check the reason? "[$ProductName:MicAssembly.lookupValue]" may be a mistake, but I don't know how to correct it.

Please use following formula in the JSON formatting.

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "=if([$InspectionType] == 'Mic Assembly', '[$Product_x0020_Name_x003a__x0020_]', 'NO')"
}

Result:
