Fill a variable with a selected field in a table

Hi everyone!

I was wondering if there is a way to fill a variable with the content of a selected cell of a table.

I'm woking on a formulary that shows a table as a result. This table has X lines and 7 columms. I want to make something to be able to get the value of one of those cells, specific the cell that the user selected, and fill a numeric variable with that value.

Is it possible or am I asking too much? :)

Thanks in advance and a great weekend for everyone.
