Can someone help me create a formula in Airtable? In my 'Services' table, I have fields for 'Height', 'Width', 'Depth', and 'Unit of measurement', which is a single select field with options for 'cm.', 'in.', and 'mm.'. I also have a field called 'Measurement'. I want the 'Measurement' field to display the number values for each of the height, width, and depth fields, separated by the character 'x', and to include the appropriate unit of measurement based on the selection in the 'Unit of measurement' field. If any of the height, width, or depth fields are empty, I don't want the 'x' character to be included. Additionally, if the unit of measurement is 'in.', I want it to display as 'in', if it's 'cm.', I want it to display as 'cms', and if it's 'mm.', I want it to display as 'mm', between each character."
