Re: Argument not being accepted by function

[James C. W. <jfc...@ya...>]

Hi,

Is this what you meant by quotation marks?
playVid("stairDoorOpenLeft", 20, 4, 333, 400, 15)

If so, there's apparently another problem. Now pipmak gives another error message, but this time it says that "global  patch" is a "nil value", which is odd because it's obviously nothing of the sort, it's just a regular patch object, as you can see in my function, not a global.

Thanks,
 James

The function looks OK in that regard, so if the above is your actual call, then probably the variable stairDoorOpenLeft actually has value nil - have you checked that? Or possibly you didn't mean it to be a variable, but a string literal, i.e. you forgot the quotation marks?
