I am playing around trying to teach myself actionscript and I’m getting frustrated with a simple dynamic textbox. I have a main movie with just one frame and in the frame actionscript I have :

```
newitemwidth;
totallength = 10 + newitemwidth;

```

I have a button on this main movie that on release, among other things, has:

```
newitemwidth = 115;

```

I have a dynamic textbox on the movie as well with the variable set to:

```
totallength

```

When I test the movie, the textbox shows 10, but when I click the button it doesn’t change to 125 with the added newitemwidth. Am I missing some rule about global variables here? Thanks for your help.
