Compere String In Crystal Rep

HI


I HAVE A SQL LINE LIKE"

select * from table
where numb like 'mao71'


now

i wrote the formula in my js page and sending it to a mo.rpt that i made

now i dont know how to compere the strings

i wrote

url=document.getElementById("sesuserprint").value;
forma="({PRINTALL.numb})" + " %3d " + URL;

(url is a value that i get from an inputbox in my html)

but it return an error " invalid formula......" becuse i am trying to compere a text value in "=" and not in "like"



my question is?

how do i write "like" in crystal report?
