Quotes around my list or module names are removed after I have typed them and pressed Enter. | List or module names containing numbers or the full point are enclosed in single quotes to delimit the name. If the item is recognized, encapsulating quotes are removed. Note that if both the module name and the list item contain numbers or a full point, each individual item must be encapsulated. For example, a module named Sales 2017, with a line item named Region 3 would be called 'Sales2017'.'Region 3' in a formula. |
