allval=allval+parseFloat(theForm5.totmountx2.value); 
allval=allval+parseFloat(theForm5.totmountx3.value); 
allval=allval+parseFloat(theForm5.totmountx4.value);

Use

theForm5['totmountx'+ i].value

Also, it should be:

var allval = 0;
for (var i = 1; i <= seq; i++) {
    allval += parseFloat(theForm5['totmountx'+ i].value);
}

Otherwise you try to initialize the variable multiple times.
