variable1 = parseInt(document.getElementById('startGroup').value);

Or you could use parseFloat if you are expecting decimal numbers. Or even Number() function, it both covers integers and floating numbers.

variable1 = Number(document.getElementById('startGroup').value);

apart some readonly values exceptions, all the attributes values are returned as strings in javascript, so that you must transform them into numbers, using, according to your needs, some methods: Number(), parseInt(), parseFloat()... a.s.o
