Hi, I'm trying to generate something like a report at the end of my survey. Therefore I have some questions:
1. If I want to be more flexible I have to define my own functions in PHP or Java Script. Therefore I would have to write my own function to the template or directly to the Expression Manager php-files. If I extend the Expression Manager would this break the update compatibility?

2. More important to my is the question if I can iterate over all question using the self variable? In my case I have about 50 questions. To check for occurence of single answers results in a very large expression. For example I used this expression in an older survey to check the proportion of the answers:

{if(sum(A1.value==3,A2.value==3,A3.value==3,A4.value==3,A5.value==3, B1.value==3,B2.value==3,B3.value==3,B4.value==3,B5.value==3,B6.value==3, C1.value==3,C2.value==3,C3.value==3, D1.value==3,D2.value==3,D3.value==3,D4_1.value==3,D4_2.value==3,D4_3_1.value==3,D4_3_2.value==3,D4_3_3.value==3,D4_4_1.value==3,D4_4_2.value==3,D4_4_3.value==3,D5_1.value==3,D6.value==3,D7.value==3,D8.value==3,D9.value==3,D10.value==3,D11.value==3,D12.value==3,D13.value==3,D14.value==3,D15.value==3, E1.value==3,E2.value==3,E3.value==3)==
sum(A1.value==2,A2.value==2,A3.value==2,A4.value==2,A5.value==2, B1.value==2,B2.value==2,B3.value==2,B4.value==2,B5.value==2,B6.value==2, C1.value==2,C2.value==2,C3.value==2, D1.value==2,D2.value==2,D3.value==2,D4_1.value==2,D4_2.value==2,D4_3_1.value==2,D4_3_2.value==2,D4_3_3.value==2,D4_4_1.value==2,D4_4_2.value==2,D4_4_3.value==2,D5_1.value==2,D6.value==2,D7.value==2,D8.value==2,D9.value==2,D10.value==2,D11.value==2,D12.value==2,D13.value==2,D14.value==2,D15.value==2, E1.value==2,E2.value==2,E3.value==2)
,"<div>equal</div>",
if(sum(A1.value==3,A2.value==3,A3.value==3,A4.value==3,A5.value==3, B1.value==3,B2.value==3,B3.value==3,B4.value==3,B5.value==3,B6.value==3, C1.value==3,C2.value==3,C3.value==3, D1.value==3,D2.value==3,D3.value==3,D4_1.value==3,D4_2.value==3,D4_3_1.value==3,D4_3_2.value==3,D4_3_3.value==3,D4_4_1.value==3,D4_4_2.value==3,D4_4_3.value==3,D5_1.value==3,D6.value==3,D7.value==3,D8.value==3,D9.value==3,D10.value==3,D11.value==3,D12.value==3,D13.value==3,D14.value==3,D15.value==3, E1.value==3,E2.value==3,E3.value==3)>
sum(A1.value==2,A2.value==2,A3.value==2,A4.value==2,A5.value==2, B1.value==2,B2.value==2,B3.value==2,B4.value==2,B5.value==2,B6.value==2, C1.value==2,C2.value==2,C3.value==2, D1.value==2,D2.value==2,D3.value==2,D4_1.value==2,D4_2.value==2,D4_3_1.value==2,D4_3_2.value==2,D4_3_3.value==2,D4_4_1.value==2,D4_4_2.value==2,D4_4_3.value==2,D5_1.value==2,D6.value==2,D7.value==2,D8.value==2,D9.value==2,D10.value==2,D11.value==2,D12.value==2,D13.value==2,D14.value==2,D15.value==2, E1.value==2,E2.value==2,E3.value==2),
"<div><b>OK</b></div>",
"<div><b>bad</b></div>"
))}

or for occurence:
{if(sum(A1.value==1,A2.value==1,A3.value==1,A4.value==1,A5.value==1, B1.value==1,B2.value==1,B3.value==1,B4.value==1,B5.value==1,B6.value==1, C1.value==1,C2.value==1,C3.value==1, D1.value==1,D2.value==1,D3.value==1,D4_1.value==1,D4_2.value==1,D4_3_1.value==1,D4_3_2.value==1,D4_3_3.value==1,D4_4_1.value==1,D4_4_2.value==1,D4_4_3.value==1,D5_1.value==1,D6.value==1,D7.value==1,D8.value==1,D9.value==1,D10.value==1,D11.value==1,D12.value==1,D13.value==1,D14.value==1,D15.value==1, E1.value==1,E2.value==1,E3.value==1)>0,"<div>You answered dog on at least one answer</div>","")}
3. If I write my own Java Script function in the template how can I access the questions (e.g. E3.value)?
thanks in advance
