Wiremod Expression 2 Help

So I want a code where its possible to save a value if it changes. For example I am using a MoneyPot in DarkRP and if someone donates some money in it the EGP Screen will save it’s value and after someone donated again it should not disappear just go 1 line deeper and write it again.

For example someone just donated 100 dollars. Then 5 minutes ago someone donated 500 dollars

I----------------------I

I 100 I I Money I [E2 CHIP]
I 500 I I_Pot____I
I 0 I
