cannot convert value "NA" of type text to type numeric

[kamlesh7777]

Hello All!
I have  converted a blank value to NA of two of my parameter 
i.e. A and B both datatype is currency if value is blank then convert it to NA using isblank dax
noew i'm trying to achive percent format of calculation
i.e. A/B 
,but there is a region where both A and B values are BLANK and when indiviually represented it shows NA on card visual.
DAX :- % revenue  = Divide(A,B)
and in percent format.
But I'm getting error as below screenshot,

I hope i'm able to make you understand it,
Thank is advance.

Hi, 

the problem is that you have text values ("NA") in your columns. PowerBI can't perform a division on text values, which is why it's throwing this error message.
