I am trying to build a function that will update the attibute of a dynamic block with multiple lines. however I also want to adjust the line spacing within the dynamic block. How do I go about referencing this function?

basically modifying this within the dynamic block

See these properties of the MText class:

   LineSpacingStyle

   LineSpacingFactor

   LineSpaceDistance

thanks I reposted it there.

I think I tried those already and they don't work. I think the text inside belongs to multiline text instead of Mtext. Although I can't be sure of that
