"Web_Access".DQ0a is the name of the PLC tag I need to change, using a form input in that method is how the PLC expects it. The manual has it written as I have, but with the button a submit type instead (and no onclick).
Why is that invalid by the way? Can't you have whatever you like in the name string as long as it is between "_" or '_' ?
I think the problem must be in the post part because when I take out the comments on the document.write(parameters); line I get the same result in Firefox and Chrome: %22Web_Access%22.DQ0a=1
