Trying to create a calculation but it won't work...

Question

Hi!
I'm using Adobe Acrobat 8.1 for Mac.
I've created a form and I need to enter what I assume to be a custom calculation script.
The field named Text49 needs to be the result of the field named Text46 (manually entered value) multiplied by .062
This is what I've entered in the custom calculation box in Text49:
var v1 = 1 * this.getField("Text46").value;
event.value = v1 * .062;
But it's not working correctly. It'll work the first time when I manually enter a value in Text46 however when I change the manually entered value in Text46, the result in Text49 doesn't change.
Also, Text49 doesn't show up in the box for setting calculation order.
I'm sure it's something with my formula but I can't figure it out and don't know where to look.
Can someone please help?
Thank you so much!
Diane

I must have messed something up because now it's not working at all. :(
In response to your question, no there's no script on Text50 but there is custom validation on both Text49 and Text50.
The validation script for Text49 is:
var f = this.getField("Text49");
f.hidden = (event.value < .0000001);
The validation script for Text50 is:
var f = this.getField("Text50");
f.hidden = (event.value < .0000001);
I've tried it with and without the validation script and it's not working either way.
I've tried it with Text49 and Text50 as "hidden" and "visible" and it's not working either way.
The one constant I'm finding is that even when I do get the calculations to work, when I save and close the form and re-open it the calculations have quit working.
I'm at a loss... :(
Any ideas?
Thank you!
