The result
main(27,3):ERR :No matching signatures to 'SetPropActiveAndFade(string@&, const bool)'

My Script

You forgot the last part of the SetPropActiveAndFade

SetPropActiveAndFade(string& asName, bool abActive, float afFadeTime);

asName - internal name


abActive - nothing to add


afFadeTime - time in seconds until prop fully fades
