How can I edit a text on a custom sign?

[Swjosdotschka]

Hey there,

title says it all. How can I edit a sign were I entered a text a while ago? Whenever I click on it, it just tells me which sign it is, but does not let me edit it.

Thanks for your help in advance!

Is the sign attached to a post or building , If so you have to go into
group edit mode and then click on the sign again so that it only chooses that part

Click on the whole thing , then click group edit mode at the bottom of that window , then click the sign itself

edited . i went into the game to see what it was called

Could you post a pic screenshot of it when you have it selected?
