Page Parameter not working on phone preview!

Hi

I’m passing a page parameter between two pages and analyzing it using an IF statement in page mount logic on the target page
The IF flow function is a formula as below.

NOT(CONTAINS(params.Order_Info_Pass, “0”))

If the parameter is not 0 then true!

On the web preview this is true (as expected)
On the appgyver app phone preview it is always false (not as expected)

Any ideas?

Solved.

I just needed to step back for a minute

NOT(IS_EQUAL(params.Order_Info_Pass, “0”))
