DateAdd - Syntax Error

[DubCap01]

Could someone in the font of knowledge advise me what part of this statement is incorrect please? I am baffled trying to add 45 minutes to a time of 16:45
All the fields listed have the format Short Time, and have data, I just cannot update the first field listed... I am getting syntax error.

Me.CurrCycleStartTime = DateAdd('n', "Forms!FrmCycleData!LastCycleTime", "Forms!FrmCycleData!LCCT")

thanks in anticipation
