Code:

var zip = zipfx();

This executes the function zipfx and assigns the return result to the variable zip. But it runs straight-away, before the form exists, so it returns an error as it cannot refer to forms['zipSearch'].

Code:

var zip = zipfx;

Assigns the function to the variable, so that it could be executed later by calling

Code:

zip();

FYI It is preferable and more modern to use IDs rather than names. In particular, form-names are deprecated/discouraged.
