I have written a macro that opens IE to the following web page

http://adds.aviationweather.gov/metars/

I am able to select certain options and values using the "set ipf"
method. However, I am unable to programmatically select either the
"Raw Format" or "Translated" radio button using the "set ipf" method.
In other words, the following code does not select the "Translated"
radio button:

Set ipf = ie.document.all.Item("std_trans")
ipf.value = "translated"

Similarly, I can't select between the "METARs" and "TAFs" checkboxes.
I've included the relevant source code below. Any help on how to make
these selections would be appreciated...TIA, Ron
