Please help. I'm stuck

hello all,

thanks to the help i got in this forum, I solved a big problem and now I have another .
I worked on an animation yesterday then saved it in synfig file. today, i opened it to carry on with my work , but couldn’t edit anything.

whenever i tried to change the size or whatever, i got that message

The value you are trying to edit is in a composition
which doesn’t seem to be open. Open that composition and you
should be able to edit this value as normal.
What should I do?

Thanks

This is the exact same question you posted here, viewtopic.php?f=11&t=3522&p=14916#p14916.
Please do not double post. I’m locking this thread.
