Passing the current Record to a function

I created a function that I wanted to use to do a calculation when a custom column is being created.

 

I defined the function something like...

 

(Source as record, CheckVal as number) =>

 

When I try to use the function I am passing in the underscore but the function gives an error of "We cannot convert the value null to type Record" which suggests that _ is null.

 

Any thoughts on what I am doing wrong or an example of how to make this work?

 

Many thanks,

 

Trevor

    Hi Trevb,

     

    What's do you mean by "create a function"? So far as I know, there is no an place where we can create a function. So in your scenario, please elaborate your issue, if possible provide us some screenshots, so that we can make further analysis.

    Where do you pass that "_"? For example, is it in Table.SelectRows(table, each func(_, checkVal)) ? Can you put the whole M code here?
