Need help with string field formula

Question

What I am trying to accomplish:
The report has item numbers and each item number has the
potential to be associated with up to three u2018binsu2019. So the fields are u2018item
numberu2019, u2018bin1, u2018bin2u2019 and u2018bin3u2019.
I tried to write a u2018if thenu2019 statement that would only show
records that had a value of less than 1 in each u2018binu2019 field. When I try to
write the statement I get a message that says u2018A string is required hereu2019 and
it highlights the number 1 in my statement. I have a feeling itu2019s because the u2018binu2019
fields are string fields and not number fieldsu2026? So I am not sure the proper
procedure to correct this. Thus help is needed and appreciated.
Here is what I wrote:
if {IC_LOC_HIST.BIN_NAME_1} < 1 then
{IC_LOC_HIST.BIN_NAME_1}
What is correct way to write a statement that will show me
the zero values in each column of bin fields?
Thanks!

You must have a non-numeric value in there somewhere - up in the top left of the formula editor window, it'll show you the variables you've passed to the formula, which should help track down what's going on.
You could try and check that the value is a number first by using something like:
if isnull({IC_LOC_HIST.BIN_NAME_1}) = false and isnumeric({IC_LOC_HIST.BIN_NAME_1}) = false and then "Error - Should be a Number!"
else
if isnumeric({IC_LOC_HIST.BIN_NAME_1}) = true and tonumber({IC_LOC_HIST.BIN_NAME_1})<1 then {IC_LOC_HIST.BIN_NAME_1})
