Html and dynamics txt :tags in txt files?

Hello everybody !
I tried to make my dynamic text an hmtl text but it only works if i do this [AS]loadText = new loadVars();
loadText.onLoad = function() {
contenu.text = this.contenu;
infoperso.text = this.infoperso;
infoperso = infoperso.htmlText="<a href=‘mailto:[email protected]’>[email protected]</a>."
this is working good but what do i have to do i want a large piece of text with bold or colored characters. I tried to put the html tags in my text file but when the file is loaded it shows the html tags.
I’ve read some similar threads but don’t understand it very well, can someone help me with it?
edit a bug? it changed the color of my txt alone

are you also setting that text to the htmlText?

(ps the coloring was because you didnt close your quotes. I fixed it)
