Widget date help!

Hi there,

I am trying to use the widgets to display the previous 30 days but I am having issue with the period section. In the scr= if I put say:

period=month&date=2016-07-07

it works fine, but what I want to do is have the widget constantly show the last 30 days but if I try things like:

period=month&date=last30

I just get errors.

Can anyone help please?

Thanks,

Doomie256

try with period=month&date=yesterday
