Using TimeEQ for time frame with TagTot error

I am trying to put together a tag total function based on the time that a tag is equal to a specific value.  I have the equation set up as below.  When I evaluate the equation I receive an error that says "Invalid expression "WFE_A_MODE"    I can evaluate the TimeEQ equation separately and it runs fine.


TagTot('FC-9918.PV','(TimeEq('WFE_A_WFE_MODE.PV','*-30d','*',"Production - 1st Pass"))')


Thank you for the help.
