mob
    verb
        Cook()

The reason this isn't working is because "usr.SaltValue" is a string (or a text), not an actual integer that can be used in calculations. What you want to do is use text2num(), or just prevent usr.SaltValue from becoming a text value in the first place?

I Heard about Text2 num but never knew how to use it,mind please leaving me with a small example of how it works?
Thanks.

Instead of this:
if(usr.SaltValue>=20)



Do this:


if(text2num(usr.SaltValue)>=20)

It would be better to put it on the line with winget:
src.SaltValue=text2num(winget(src,"Salt.Saltbar","value"))

instead of
src.SaltValue=winget(src,"Salt.Saltbar","value")

That way, src.SaltValue is always a number, and you don't need to write text2num(src.SaltValue) every time you want to use it.
