I need to dynamically translate points 20 metres from their original point to a suitable cartographic position. I have a rotation value stored in a rotation attribute.
I cannot use this tool right because I cannot give values when using the function cos ("rotation") * 20 or sin ("rotation") * 20
Only number inside ' (single quotation marks) are accepted. How I can use function inside double offset definition?
Sorry about Finnish interface!

If you add a textfield to the feature containing something like20,50the offset works.

You need to transform each number into string representations, and combine those with a comma. Based on your screenshot above, the proper expression would be:
to_string(cos("rotation")*20) || ',' || to_string(sin("rotation")*20)
