With [url=https://wiki.garrysmod.com/page/net/WriteInt]net.WriteInt[/url] you need to provide the bit count as the second argument, you could just set it to 32 if you're not sure. If you want to avoid doing this, you could try using [url=https://wiki.garrysmod.com/page/net/WriteFloat]net.WriteFloat[/url]
