passing multiple arguments to function annyang (not just voice commands)

Question

I am trying to pass two arguments to my function fill_node: 1) a named-variable and 2) the data type such as mm, kg, etc. Since mm, milimeter are the same, i grouped them into one data type and passed it as the argument, entry type to the function: fill_node(entry,entry_type)

however the browser gives the following error:

Uncaught ReferenceError: tag1 is not defined
    at print.js:57

Here is my command code:

var material = {
    ':tag1 mm':fill_node(0),
    ':tag2 millimeter':fill_node(0)
}
var weight = {
    ':tag3 kg':fill_node(tag3,1),
    ':tag4 kilo':fill_node(tag4,1),
    ':tag5 kilogram':fill_node(tag5,1)
};
