Problem: What I want to do is select a month and then have a PDF file names SL_mmm.pdf display where mmm is the month passed from the dropdown. Both the *.php file and the *.htm file are in the same directory with the PDF file in a subdirectory under that. What is happening is on the htm page I am picking Feb and hitting Go, then the browser shows website/PVETest.php?month=Feb Then I get page not found 404 error but it is there. It is like the htm page is not really getting to the PHP file.
