Repeating output

[CutieDie]

I have a bit of code thatis supposed to increment through an xml file once it detects the correct input, but it keeps repeating the output(audio) once it increments to the next item in the file. I need to know why its happening and how to stop this. Someone help me please.

Here is the code
