Reply To: Is it possible to hide section nos. while setting text vaiables?

I assume these section numbers appear as text in the headings, and you want the running heads to inherit from the headings but without the numbers?

You could use GREP to apply a character style to everything in the heading except the numbers, and then base your text variable on that character style. The character style doesn't have to have any formatting, so it won't change the appearance of the text.

For example, you could use the GREP pattern: (?<=d.dt).+$
This will find any text after a number, a dot, a number and a tab, up until the end of the paragraph. You'll also need to put the paragraph style of your heading in the find format box.
