If function with division expression

[Cameron94]

This is my current calculation:

column(7)/column(11)

Usually I would utilize an if statement like this:

If (column(7)/column(11)>0,column(7)/column(11),'') 

Which would show all available numbers over 0. However this expression doesn't work as expected.

So was wondering if it is possible to achieve something similar with a different approach. 

Thankyou

Instead an if-loop you may try something like:

rangemax(column(7)/column(11), 0)
