Detect Variable Change

so im coding right now a stock simulation game and i have a text that should detect how the stock has changed and write it down in new line, but i dont know how the action should look like

So you want to know when the text changes?

If so then you could try coding :

IF Variable <Variable

I am actuallt not too sure whether this works

but it is worth trying if you would want

Radkampfwagen

yea thanks, that works, so it detects if it changes, but i really want to know what changes, e.g. -2 or +4

well could you show us a screenshot of your event sheet please so we can help
