I just want to do what should be a very simple multiplication.  
When a number in “A” is entered, multiply it by .001 and return it in “B”. In excel it would look like in cell B1: “=A1\*.001”. Should be so easy and I’m not sure what I’m missing. Thanks for any assistance.

You’re referencing two variables, A and B, but you’re not getting the value from the text input component. You’re also running two different sets of code when A changes. That’s going to create unpredictable results.

You need to do this:

```auto
When A Changes
   Set app variable A to Text Input's Text
   Set app variable B to A x 0.001
   Set B's Text to B

```

Also, a simplified but less useful version would be:

```auto
When A Changes
   Set B's Text to Text Input's Text x 0.001

```
