How do you nest/combine Smart Values?
I'd like to check to see if the first 9 characters are numeric.
The format of "valid" values from the source of record is 123456789_12 or #########_##
This provides the first 9 characters successfully ->{{issue.field.left(9)}}
AND
This provides the result if it's numeric successfully -> {{issue.field.isNumeric()}}
How to I combine these to see if the first 9 characters are numeric from this entry? 123456789_12
