Your left curly on line 61 is mismatched. It shouldn't even be there. Also, you're checking if the player has -1 of the item 26131; I think it's safe to assume you meant to check if the player had at least 1 of the item.

if (countitem(26131) < 0) { goto noring;

I could rant about why you shouldn't use goto, but to put it simply: it's just bad code - and wasn't used properly, at that. You can't (or shouldn't, if for some reason you can) use a goto within a function.

Instead, remove the checks from each case and place it outside of the function call. I added the check after line 26, before the player is given the shop menu selection. You can replace the contents of the check's script with what you had in your noring label.

Code:
mes "[Training Trader]";mes "Each shop use different training points acquired from your training";next;    // <- Line 26 [Via] .@coin = 26131;    // Coin item ID.@amount = 1;	  // Amount required // Check coinsif (countitem(.@coin) < .@amount) {    mes "[Training Trader]";    mes "You need at least "+ .@amount +" "+ getitemname(.@coin) +" to access these shops. Come back later.";    close;}
