string formatting from date/time wave

hi,

I built a function to format a string (gdasfile_str) following values in a date/time wave. Code is hereinafter. What is strange is that the last if statement actually doesn't work properly, and cannot figure out why... It is mainly for determining the week number in a month, and when going from 01/02/2015 (as a example) to 01/03/2015, the 7 first days are good (week="w1"), but then week="w2" for all other values... Experiment is also included.

Any help would be great!!
Thanks a lot

Hi J-E,

it should be (day>=8 && day <=14) and also && instead of || in the following elseif conditions.

nevermind, thought it was a more tricky mistake, but I actually used OR statement instead of AND....
sorry for "trolling", this post can be deleted.
