Problem with If statement using blanks

[manikantakommur]

Hello Guys,

I have used this If statement to find loading status, but instead of considering only blanks it is also considering zeros and giving false values. How to solve this  

Loading status =If(('AC'[loading end date]=BLANK()&&'AC'[loading start date]=BLANK()),"Not Loaded", "Loaded")

I'd appreciate suggestions on how to deal with this problem.

Thanks,

Manikanta

Trying using the ISBLANK() function (https://docs.microsoft.com/de-de/dax/isblank-function-dax)

For example:
IF( ISBLANK('AC'[loading end date]) &&  ISBLANK('AC'[loading start date]), "Not Loaded", "Loaded")
or 
IF( ISBLANK('AC'[loading end date]) || ISBLANK('AC'[loading start date]), "Not Loaded", "Loaded")
