A formula such as '[CLIENTAGE] + 10' could be evaluated and resolve to a calculated value or be intended as literal text. In most situations you can determine the intention, but some are vague, namely the Label Question's Label Text property and the Projects File Name property. These two fields should start with an equals symbol when the text provided is intended as a formula as depicted below.
Label Question 'Label Text' field
