Help, why won't it let me count trees

So i've got this trigger. It contains an EnumDestructiblesInCircle call. This relates to a function called Tree_Counter. Using Lord Vexorian's Handle Variables, (did he do those ? Or did he get them from somewhere ???) it gets an local Integer or a Real (tried both) from the main action function called trees, then does:

set trees = trees + 1

and again puts the real or integer into the gamecache for further use. Now my problem is i'm getting "invalid argument" errors from that line! Why ?! It's a local real/integer declared, took from the gamecache, being processed and put into the gamecache again. And that line is the only one giving me those compile errors. After looking at a converted GUI trigger, i tried set trees = (trees + 1). But that ALSO gives me invalid arguments ?! What am i doing wrong ?

x.X we should sticky a thread, "problems with the WE script checker thing".

Look on the line before it, the problem might be there.

We would have to see the script. the only script checker i've found to be completly pointless is expected name. so you may really have an invalid argument.

You mean the syntax checker really points to the line above ? *looks*

Ok i found the error. It was a function that couldn't be used that way:

local real trees = GetHandleReal(t, "trees", trees)

I had to write a function for getting the Handle Real and use it instead.

Thx for pointing that out ! ^_^

Sometimes it does... >.<

Basically, if it says sth is the problem, that sth is by no means guaranteed to be the problem.
