Issue:
Customer has scenarios where they have a column with no formula (blank) and want to check if it's null because no one filled it in.  Does the ifnull(^fieldname^, xyz)@ allow for  an empty cell as null?

When using a column reference and that reference does not contain any value (blank) then evaluation of the expression on IE 11 crashes with the error 

TypeError: Unable to get property 'indexOf' of undefined or null reference
