appending variables to URLs

I have built a Search Engine GUI that uses a GetURL action to inform a cgi script. It uses a input text field with the variable name, searchString. I Send variables using GET. When a search is executed, my variable is appended at the end of the URL as expected, but preceeded by a question mark rather than an ampersand which causes the action to fail.

My resulting URL is appended with:
?searchString=hot+dog

rather than:
&searchString=hot+dog

Can anyone tell me how to replace the question mark with an ampersand? Or how to work around the problem?

I am using Flash5.0a, but publishing as Flash 4.
