I have been working on a questionnaire results page which takes the values from the questionaire on the previous page, calculates a score then plots their results on a grid. this all works fine, what i am a little baffled about however is, how do i dynamically add table rows/cells to an already existing table? if i use document.print() it just overwrites all the existing html etc.

here is the function i currently have to output the information:

function summary(){

var resultArr = new Array();
for(i=0;i<14;i++){
if(newValArr[i]==100){
resultArr[i] = "Strongly Agree";
}
if(newValArr[i]==75){
resultArr[i] = "Agree";
}
else if(newValArr[i]==50){
resultArr[i] = "Disagree"
}
else if(newValArr[i]==25){
resultArr[i] = "Strongly Disagree"
}
else if(newValArr[i]==0){
resultArr[i] = "Not my job";
}
if(i==13){
//alert('broken out of strongly agree loop');
}

}
for(i=14;i<27;i++){
if(newValArr[i]==100){
resultArr[i] = "Always";
}
if(newValArr[i]==75){
resultArr[i] = "Usually";
}
else if(newValArr[i]==50){
resultArr[i] = "Occasionally"
}
else if(newValArr[i]==25){
resultArr[i] = "Never"
}
else if(newValArr[i]==0){
resultArr[i] = "Not my job";
}
if(i==26){
//alert('broken out of always loop');
}
}


for(p=0;p<14;p++){
if(resultArr[p]=="Agree"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');

}
if(resultArr[p]=="Disagree"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');
}
if(resultArr[p]=="Strongly Disagree"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');
}
if(resultArr[p]=="Not my job"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');
}
if(p==13){
//alert('broken out of summary table creation loop 1');
}

}
for(p=14;p<27;p++){
if(resultArr[p]=="Usually"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');
}
if(resultArr[p]=="Occasionally"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');
}
if(resultArr[p]=="Never"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');
}
if(resultArr[p]=="Not my job"){
document.write('<tr><td colspan="2">');
document.write('<p>'+(p+1)+'. You answered: '+resultArr[p]+'</p>');
document.write('</td></tr>');
}
if(p==26){
//alert('broken out of summary table creation loop 2');
}

}

until this morning i had the entire page being outputted using the document.write function, but after reading a response to another post i made, i took all the print()'s away and split the js up into several functions. everything works fine on my page, apart from this section (which is used to print a list of answers a user gives to the questionnaire)

I have a main table and i want to basically get this function to write html to append specific table rows/cells without over writing the rest of the html.

Any help would be much appreciated!

Thanks,

Mike
