File Name Validation

You might want to edit this and sort out whatever funny stuff occurred to its formatting when you pasted it in here, because at present it's basically unreadable.

Ohhhh, I didn't notice.

I just changed it, can you see it well?

that's better.  i'm not sure i understand the issue though.  are you just saying the validation doesn't work?

one thing I do notice is that you seem to have spaces in your preferred naming convention ("inventario dic 2023") but the string you're checking the filename against does not have any spaces built in.

That is, this code:

""INVENTARIO" & upper(tostring(datetext(today(), "MMM"))) & upper(tostring(datetext(today(), "YYYY")))"

would output "INVENTARIODEC2023", not "INVENTARIO DEC 2023".

Instead you can try this:

a!localVariables(
  local!var2,
  
  {
    a!fileUploadField(
      saveInto: local!var2,
      value: local!var2,
      label: "File Upload",
      labelPosition: "ABOVE",
      validations: {
        if(
          fv!files.name = "INVENTARIO " & upper(tostring(datetext(today(), "MMM"))) & " " & upper(tostring(datetext(today(), "YYYY"))),
          "Ingrese un documento nombrad correctamente.",
          {}
        )
      }
    )
  }
)

Note how this has been updated

"INVENTARIO " & upper(tostring(datetext(today(), "MMM"))) & " " & upper(tostring(datetext(today(), "YYYY")))

and presumably returns the value you actually wanted:

I tried that you mentioned and it works!!
Also my profile was setted in English, so i changed it to Spanish!

Thank you, Mike

Cool, glad to help.

One final thing to add, this is a good example for why I like abstracting certain things like this (like assembling of the validation string) into local variables - it makes it a lot easier to see, understand, and troubleshoot (and re-use if necessary).
