if(
  find("..", "123..456"),
  "ERROR",
  "OK"
)

In addition to the existing set of validations for decimal values, Throw a validation for  values like "3.6.5".on top of this code

if(
  ri!txt = 0,
  "",
  if(
    or(
      not(
        rule!APN_isBlank(stripwith(ri!txt, "1234567890,."))
      ),
      find("..", ri!txt)
    ),
    cons!CR_APP_FX_VALIDATION_MESSAGE[4],
    if(
      (len(ri!txt) - find(".", ri!txt)) > 9,
      cons!CR_APP_FX_VALIDATION_MESSAGE[3],
      if(
        ri!txt < 3.5,
