Dear Nicki,
how will your identifier look like? Why doesn`t it work like this?
v1=2 v2=105 v3=27 v4=7
ident= v1*1000000000 + v2*1000000 + v3*1000 + v4 = 2105027007 (with 3 digits/variable)

Dear All,
I apologise if this question is simple but I really can't figure it out.
In creating my chk file, I need to ensure that four of the variables contain a certain number of digits. I know this is normally controlled by number fields the .qes file. However, in this instance I need zeros to be included at the beginning (eg. 0003) so that all responses contain the same number of digits. This is because I will be putting these 4 variables together to create a 10 digit identifier later in the chk file.
At the moment, whenever I enter 0003, the zeros are removed and I am left with just 3.
Does anyone know if there is a way to ensure the zeros remain, and to ensure that each variable entered contains 4 digits?
Many thanks in advance for your advice!
Nicki
