Well I had a red Suteki attached to my watering can... then I went to Goran and got it updated with the 3000G thing. Then it said 0/3 at the top.... Ok, so I went to Charlie and asked him to put the blue one on, in addition to the red and he said "You can't put this here"... So I just played around to see what might fix the problem and I ended up removing the red stone... When next I looked at the slot thing... it now said 1/1.... did I just waste 3000G.... and how do I put in more than one stone? I thoguht all you had to do was go to Goran...
I haven't played for a while but you can't upgrade a tool (if I remember correctly). You can buy tools from Goran with more empty slots. So I think you've bought another watering can with 3 empty slots (and you still have the one with 1 empty slot). Perhaps you tried to put the blue stone to the 1slot-watering can (but there was already the red one). Be sure to choose the 3slot-watering can for the red and blue stone.
