Hi,

I have this code but I receive a type mismatch error. If I change this line:
document.getElementById(rowId).parentNode.removeChild(rowId);

to:

document.getElementById(rowId).parentNode.removeChild(row22);

it works. How can pass a variable to the removeChild?

Much thanks,
vkimura

Try this:

tr = document.getElementById(rowId);
tr.parentNode.removeChild(tr);

Thanks cxr and fsze88. Both codes work. I had to offer  fsze88 more points since he had the resolution first. Thank you both, though.
