Sharepoint list calculated column value based on checkbox
I am trying to add a formula to a calculated column I created in my Sharepoint list. If the user checks my checkbox column then the calculated value is based on another field * some numbers, if not then the value is just 0. Here is my syntax:
IF([Material Delay],([Labor (Hours)]*66)*.50),0)
Keeps saying my syntax is wrong or it is not supported. Not sure what I'm doing wrong.
