Ruby - datavision formula script

ruby-talk
1

I’m trying to set up a formula in datavision that just takes the value of
a field and divides it by 100. I’ve never used ruby before but have been
digging through the online docs for help, but I’m sitll not getting what
I need. I’ve tried many variations on the following:

{echo “{table.field / 100}”}

…but to no avail.

Can anyone point me in the right direction?

Thanks,

Jody

Use “{table.field} / 100” without the quotes. The text “{table.field}” is
replaced by the value of that field, then that number is divided by 100.
You don’t need to print or echo the result; the number is the result.

Thanks for the help. This is a great package you have here.

When I try:

{table.field} / 100

I get this error: java.util.EmptyStackException

and without the spaces (ie: {table.field}/100):

java.lang.UnsupportedOperationException: Operator “/100” is illegal

Am I doing this correctly?
