Error in Macro

[Rahim Amir Ali]

Hello to All,
Today I was running a macro in which I face this error and quite unable to resolve it.
Can anyone please help me as my office is 365

MSProject.PjDateFormat.pjDate_mmm_dd_yyy

Error is Compile error, variable not defined.

Error says variable not defined, so you have to define the variable.
Without seeing the code something in this direction.
Dim MSProject.PjDateFormat.pjDate_mmm_dd_yyy
