Single Quotation Mark

[aspnetlearning]

Hi again,
My problem is using single quotation mark result Error.
This formula:
IF(C8< 5," Don’t add lower 5.ppm.","OK")
In html
data-formula="IF(C8< 5," Don’t add lower 5.ppm.","OK")"

It works when I remove the single quotation mark. I think overlaps with html quotation mark .
I just wanted to ask. Can we use single quotation mark it?

Thanks
