I can't get my soundmod to work. I need help!

I’ve been working on a soundmod for Black Mesa that’s supposed to replace some weapon sounds. I can’t get it to work for some reason, even though i have made the sounds in the correct format (I have tried both .wav and .ogg with 44100 Hz). I have tried uploading it to the steam workshop and subscribing to it but to no avail.

What am i doing wrong?
