I’ve written the following script (print from the movie explorer) but I can’t see the inputed variables in the trace screen. What do I do wrong?

greetings,  
Han

!!! JUST GOT BACK INTO FLASH AND I DON’T REMEMBER IF THIS IS CORRECT, SO DON’T KUNG FU MY \*\*\* IF I’M WRONG !!!

I think your problem is here:

\_root[“werkgever”+nummer] = new Array ();

-Im not sure if you can use \_root as an array name, you should try something like this:

arrayName = new Array();

and i don’t think you can have anything other than an number when you call out a part of the array:

someVariable = arrayName[0]

instead of:

someVariable = arrayName[someWord]

\*\*  
if werkgever is a string try

eval(“\_root.werkgever”+nummer) = new Array()

if werkgever is a variabe try

eval(\_root.werkgever+nummer) = new Array()

Since you have a numerically indexed array - constructed using push() then you can only use numerical indices. If you want to create an associative array then you would construct it using the syntax

lunchbox=new Array()  
lunchbox[“sandwich”]=“ham and cheese”  
lunchbox[“drink”]=“milk”

if you trace lunchbox[“sandwich”], it will return “ham and cheese”

If you want to create a multi-dimensional array then use the syntax

lunchbox=new Array()  
lunchbox[“sandwich”]=[“bread”, “ham”, “cheese”]

if you trace lunchbox[“sandwich”][1] it will return “ham”

Thank you for the aswers. I found the problem. It is a silly problem. I explain: I used a MC as a button. In that case you have to write \_root. in front of each variable in the on(release)-function in the MC.  
When you change the MC into an BT then it works without that \_root.  
Very silly!

greetings,
