FOR /L loop using set command

I am throwing things at this point trying to figure out why I can not set variables inside of my for /l counter. Here is the snippet that doesn't work :
set /p startdate=Enter the Start date for log retrieval (Format: yyyymmdd)= set /p enddate=Enter the End date for log retrieval (Format: yyyymmdd)=
FOR /L %%d IN (%startdate%,1,%enddate%) DO ( set /a juld = %%d set /a jd = %juld% set /a jyear= %jd:~0,1% set /a jyear=%jyear% set jdays= %jd:~1,3%
more code is here but the initial %%d value is not getting set to the variable. Yes, I am new to batch programming and there definitely could be something I am missing. I have tried the delayed variable expansion and so forth but nothing seems to work.

FOR /L %%d IN (%startdate%,1,%enddate%) DO (
set juld=%%d
set jd=!juld!
set jyear=!jd:~0,1!
set jyear=!jyear!
set jdays=!jd:~1,3!
The delayed expansion acts on variables marked by ! not the usual %. Never insert spaces before and after the = in SET statement. The /A switch is required for arithmetics only not just numeric assignments.

I don't see the pointf of there, but I'll stay tuned:
set juld=%%d set jd=!juld! set jyear=!jyear!
