Empting a numeric field

Numeric fields default to 0 on load but I have been asked to change this behaviour.

I have tried

setField("MyField","","");

And it works great for the very first numeric field on my form.

Then for all others, when I load the form I get "Incorrect format of input string".

Baffled as to why it would work for 1 numeric field and not the rest.

Anyone got any sneaky tricks to suppress that default 0?
