well i updated my server to epilogue a few months back. and last week i desided to move my Custom Gm shop from multicells to merchants_shop and ids .

Everything is correct, the sqls all all correct the htm too. i get the buy/sell/refund window i choose items they get transfered in the buy box but when i click on "buy" i cant get the item and i get that error on consode :

only 1 day passed and already bumping? It's not that critical, you could have re-read all your code (i believe you saved the sql query in a file) and maybe already found your problem...

[hope]

you have a error in one of your custom buylists

yeah thank man. I had invalid items on my merchant buylists.( not all items can be sold on gm shop)
