I am trying to read a cell and then have an IF- flow based on the value ( NULL or NOT )
I tried the following:
reading a cell - converting the variable to string - getting the length if the string- check if length=0
I get the following error both times:
FILE has thrown an exception
Message: Object reference not set to an instance of an object. This error usually occurs when using a variable with no set value (not initialized).
Exception Type: NullReferenceException
