I'm trying to filter to hide the rolls if the cells on column "OELine Item#" are zero. It didn't work using...

IF({OELine Item#}=0,"","")

Your help most appreciated. Thank you!

If you are creating a filter, all you need is:
{amount field} <> 0

You don't need an IF formula, as that is implied within filters. Note that you are comparing the amount, not the item number itself. Or do you actually want to filter out an item number code equal to zero?
----
If you are creating a calculated column and you want to only print the value if it is non-zero, then you can do this:
IF({amount field}<>0,STRING({amount field},2),"")

This will output a blank instead of a zero.

If you want to see only the items, not miscellaneous or comment or instruction lines, you can use

{Line Type}="R"

Thanks Softrak Tech Support for the quick reply.

And also thank you, Kate Spontak. The one you gave me is what I wanted.

Have a great weekend!!!
