UDF and #NAME?

Hello
In this legacy spreadsheet
I have got the following UDF defined in a module.

Function nb_antenna(nb_sectors As Double) As Double

nb_antenna = 2 * nb_sectors

End Function


now in one of the worksheets, i have in G6 nb_antenna(D6)
and in D6 i have the value 1

which gives a value of 2 in G6

this is the legacy stuff

now when i change 1 to 2 it comes up with #NAME?

I thought it had something to do with security, and i changed the macro settings to the lowest. (what nasties should i be watching out for when i do this?)

but no dice(perhaps i am not doing the security setting change correctly

Can't see anything wrong with the code. The error #NAME usually means that the formula cannot find the function name.

Try putting the word Public before the function in the module to make it Public Function nb_antenna ... etc.

Make sure the function name is spelled correctly in the sheet.
