I uploaded the files and images.
Thank you very much.
I tried loading the file in the TaskChain module and it worked much better (see screenshot).
I will change the HotPot module in due course to treat the IMT files in the same way that TaskChain treats them.
thank you for your patience, and for introducing me to the IMT. It's a very nice tool!
that's perfect, thank you very much for your help.
