Trying to setup a filter based on Radio button Selection for the month

I have this file where there is a usage table and I want to create a filter on column D where the date is, based on the radio button selection for the month. The reason why is because at the end this is used to create a pdf file that contains the filtered section along with other sheets information (Not included) that is also built based on the radio and check buttons in the printing menu sheet. I have tried using the autofilter method to no avail for I have to pass the parameter from a different routine that identifies wich radio button was selected. My code is on sheet1.
I tried passing this as the parameter but it doesnt work:

I then called the the "usage sub(strMth)" but it errors out.

Please help

The file I sent is incomplete, as a whole the full version of the file is built to create a pdf file base on a few ranges in different worksheets. The code appears to be incomplete because of this reason, however, my challenge lies on the filtering section, that is why I did not elaborate on the rest. My goal is to create a filter based on the radio button, passing the filtering parameter from a different sub routine. The Range("DateFltr") is part of the full file version. I was trying to solve the 1004 error. Basically it refuses to set the filter on the cell where the data begins (In the full version is D13), so I tried to create a named range on D13, but it goes pass the instruction without error but the filter is not set. I tried to create a simplifited version of the file for those providing feed back (trying to eliminate "NOISE"). Back to my question: How do I set a dynamic autofilter passing the Month as the filtering parameter and the radio button as a trigger.
I appreciate your help and anyone else willing to take a shot at this knowing that it generates error 1004

Thanks, the msdn article is very valuable, I will use the value as an integer compared to the name as string.
