Hi,
all of your requirements are standard and built in.
1. login page (This is where the counting should take place)
2. greeting
3. general queries (textbox for age, option button for gender, combobox for reason for training)
4. Inquiry as to whether the customer wishes to participate in the survey (yes: go on with this survey, no go to the lkast page of the survey)
5. page with 15 select buttons, There is a separate survey for each option. The survey should be displayed sequentially for each selection.
6. Endpage with a thank you message and the submit button
1. Create a closed token-based survey and you send the link to the survey with individual passwords to the participants (click opens the survey)
2. Set in "text elements" and "presentation"
3. Up to you. You know what you want to ask.
4. "quota management" (if the answer is "No", the repondent is screened out)
5. You mean, there are 15 separate parts. Use "Condition" on group level; but depends on your design.
6. Set in "Text elements".
What you should do.
Create a small prototype of your survey and send the lss export.
Here you can address things you still don't know.
But first read the manual and you may also import some of the sample surveys
