Question Getting the number of sets the user wants to buy

[DGVaniX]

Hi, so I am making a bot and the user has a "!buy" command that also has a parameter. How do I find out what number the user enters after the command when the user enters it like this "!buy 3"?

if (msg.toUpperCase() == '!BUY' && '!BUY' == msg.toUpperCase().substring(0,4)){
				if(!isNaN(msg.charAt(5)) && parseInt(msg.charAt(5)) > 0){
					var string_start=msg.indexOf("UY");
					var nrOfSets= "";
					string_start+=3;
					for (var i = string_start; i < msg.length; i++) { 
						nrOfSets+= msg.charAt(i);
					}
					var sets = parseInt(nrOfSets);

I tried that but it doesn't work, it just skips to the last "else" which tells the user that the command is not recognized...

 

Thanks.
