When creating your service, under the Questions tab you add a question with the answer type Short Answer with numeric entry, or Multiple Choice/Dropdown with the answer options only containing numbers.
After creating this question, drag it to “Ask After Submitting a Valid Scan” section of the questions menu then save you Question workflow.
On the Advanced step under the “Capturing – Edit middleware” header check “Increment/Decrement Value”. Here, you will choose ‘With Question” then choose the question you created and whether it increments or decrements the value in the database. You must then specify a delimiter.
