I'm trying to use an open source OCR to change a scoreboard, which is supposed to work directly with vMix. I have tested following its guide and its not working.
It is based on the SetText function from the TCP API so i decided to manually test this command using Putty in telnet.
As soon as i connect i get the welcome message:

VERSION OK 27.0.0.81

Then the very first command returns an error, no matter which one i use, like TALLY for example i get the ER Unknown command, then i type it again and i get the proper answer:

TALLY OK 12 (12 is just an example)

now i try to change some text in a default GT Scoreboard, loaded on input #1 , named Scoreboard, with field names as HomeScore.Text, AwayScore.Text, CLOCK.Text.

First attempt using this command:

FUNCTION SetText Input=1&SelectedName=HomeScore.Text&Value=88
returns FUNCTION OK Completed

but nothing changes on the graphic

so i try different sintax like:

FUNCTION SetText Input=Scoreboard&SelectedName=HomeScore.Text&Value=88
same result

FUNCTION SetText Input=1 Scoreboard&SelectedName=HomeScore.Text&Value=88
same result


also tried using quotes


Any suggestion where the problem is?
