Skipping first parameter in a javascript function call?

I'm trying to make a custom block to make it easier for me to work with JS when I need it, and what I have so far requires the first parameter for the custom block to always be the same thing, and it has to remain untouched. When calling a JS function, the inputs list targets the first input it can. I need it to skip the first parameter and instead start inputting at the second parameter. Leaving a blank input as the first input just deletes the argument.
The script is messy and I'm probably not doing the most efficient style, but oh well.

I am not sure how do you want to execute code without put it into an input.

But I can say, if you don't want to write code all the time, you can add to your block definition the block code in front of parameters.
