Hi,

For now, can you check (or share) variable panel (or argument panel)? There might be illegal expression etc.

Hi,

It seems you try to add Date1 to some days even though Date1 is empty.
Perhaps you should have Default of subject blank and put Assign activity include the expression in the workflow.

i used assign activity @Yoichi

As variable panel is run before the activity, can you try the following?

First, remove default value of subject
Next put Assign activity the following expression after Assign Date1 = Now.Date

subject = "Timesheet update of "+ Date1.AddDay.......
