Paragraph starting 1 cm from page margin after heading: how?

[ToVeR]

I am having a paragraph indent problem.
I am using three heading levels and after the first two levels, my paragraph starts right from the left margin of the page. At the third level, things are a little different. The third heading is relatively far from the left page margin, so I want the text not too far away from the heading. Therefore I want the paragraph text to start 1 centimetre from the left page margin, only when following Heading 3. There is no other paragraph edition needed, just all the text in that paragraph needs to start 1 cm from the left margin.

So, I have started by creating a Heading 3, and because I need another indent for the text in the paragraph following this heading, I created a different body text entry in the paragraph styles. But the problem is, and somehow I think it is a stupid problem, I do not manage to get the text to start at 1 cm from the left margin. It always starts at the left side of the page, from the page margin, not from where I want it to start.

Can anyone tell me how to get this right?

Solved the issue myself.
Just did something wrong with the application of the style to the text.
Just made a new style, based on body text, but with an "indent before text" of 1,00 cm.

Problem gone!
