SAGE Estimating Error message "boolean not recognized"

Hello, this has happened on two of the take off templates I have been working on while trying to add bid items. I have attached a screen shot of where I have been adding the bid items in the take off templates also. Is this what could be causing the error? I don’t understand where this is coming from or what is causing this. As soon as I click the “ok” on the “string not recognized as a valid Booleon” pop up or the X in the top right all of sage shuts down completely and I have to restart, only to find the same error pop up and not be able to access the template at all.
