IF value column is blank return a string (HOW??)

[Anonymous]

Hello, 

I have a column called clicks where i only have one value and otherwise i have blanks. I want a new column called click1 where if blank = "-" , if not blank then the value. But it doesn't seem to work because it can't combine string and values. But is I choose 0 instead of "-" it work. Do anyone have a solution for this? 

Thank you in advance

Because you're not able to have a single column contain mutiple types of data you need to ensure the output is of the same data type.

I know in some programs zeros can be displayed as a hyphens (-). However, I do not see this option within Power Bi. You could always treat these values as text, but then would lose functionality.

Right, you would have to have your [Value] & "" in the first case and this would make it text so it would be compatible with a dash (-) character. But, now you have a text column and that may or may not be OK.

So how would you suggest the code to be?
