Thanks for your reply and apologies if I wasn't clear.
this is the issue I have:
my formula works, but I have a problem with identifying strings.
If I take my formula and instead of #java and #javascipt I put 29 and 30
it works perfectly
So I guess that it's a syntax problem related to "Scanning a field and identifying if there is a specific string within it"
again, if I want to "Scan a field and identify if there is a specific number within it", it works.
