Max Memory and custom Icons set

[Harbor]

Hi,

how can i write a global into a game variable? I have the Xmx variable at Minecraft and want my Global RAM Variable to be assigned to Xmx so that it is displayed correctly as max memory in the stats.

My second question is, I want the user to be able to customize his slots with a custom script/icon. Currently I checked Prompt for Variable values and the script says ${ThisService_Slots}=${ThisService_GetSloterino}, how do I get a query in there?
