I have tried several ways, but it remains in error:
(1) I have a given columpn (say ColA) in which there are empty values
(2) I want to create a new column, given the formul : If in ColA, there is blank value, then returns 'Missing', otherwise, returns 'Present'. To do this, I am using the recipe 'Cleaning' and using the formula ("add a new step")
Here is the formula and I do not understand why it is invalid
if (ColA isBlank,'Missing','Present')
Thanks for your help.
