trying to do a simple change value code based on a \<select\> selection for instance

\<html\>  
\<head\>  
\</head\>  
\<body\>

\<input name=“letter” value=""\>

\<select name=“select”\>  
\<option\>a\</option\>  
\<option\>b\</option\>  
\</select\>

\</body\>  
\</html\>

if option “a” is selected, teh value for “letter” will be “A” , and if “b” will be “B”. this is for a form but using a external pearl file for the mailing so there is already values in the html , so using the $post variable probably wouldnt work in my case. I guess all i really need to know is how to make a variable out of the selects.
