Help with DAX Query: Not including values that are 0

[AndrewDavies437]

So I currently have a DAX query like this:

Average Commission R12 =

CALCULATE(

SUM(

'Rolling 12 Month Transaction Report'[Total Income]),

'Rolling 12 Month Transaction Report'[Total Income] <> BLANK())

/

CALCULATE(

SUM(

'Rolling 12 Month Transaction Report'[Discounted Premium]),

'Rolling 12 Month Transaction Report'[Discounted Premium] <> BLANK())

What this is basically doing is dividing Total Income by Discounted premium.

I get a few values that are NaN (Not a number) because some of the values for total income and discounted premium are 0. I want to wrap this query in an IF Statement that says 

IF total income OR discounted premium == 0, then return 0, else do my formula. 

Can anyone help me write the DAX for this? really struggling as when I try to put it in an IF statement it only lets me reference measures not columns.

Thanks everyone!

@AndrewDavies437 , use divide and try

divide( SUM(
'Rolling 12 Month Transaction Report'[Total Income]), SUM(
'Rolling 12 Month Transaction Report'[Discounted Premium]))
