help passing resources between rounds

Hi everyone, I need help with this problem: I have a search and destroy map and I need the players’ gold to pass between rounds, but I’ve already done everything (even with the save point device, but it keeps giving bug) and I couldn’t. However, I have my map with my old system and the gold passes normally, I even tried to replicate the system but it still doesn’t work, normal items such as weapons, ammunition, etc. are passed between rounds, but the gold doesn’t… does anyone know? What can I do? (sorry for the Google Translate English, I’m Brazilian and I don’t know how to speak English)
