Calling Decision Table from script

[KeerthiPraV]

I have a use case I have created a decision table for auto populating category based on product. if i select any product the category should auto populate based on the product without saving the form itself 
So, I want to Use on change(product) client script. So, When I am changing the product based on product category should populate for that i have created decision table for which product which category should come.
but, problem is with I am using script include to call the decision table using DecisionTableAPI()...But its returning null.

could you clarify me...How I need to call and what is the best approach to implement my use case.

@KeerthiPraV 

so share your script include and client script?

is your script include client callable?

is your script include function getting called?

Hi @KeerthiPraV ,

If you getting null when calling script include from client script make sure you are returning the values properly for example - create an array, push the values in an array in form of string using .toString() function or adding +"". 

When you getting the return response in your client script make sure to parse that array in callback function of your glideAjax.

Please mark my answer correct and helpful if this works for you

Thanks and Regards,
