(beginner warning)

I'm trying to automate the creation of html templates to avoid link mistakes 
and I wrote this code today:

(defun dailyIndex (myDate)
  (interactive (list
                (read-number "Date: " (string-to-number (format-time-string 
"%d")))))
  (setq baseCSSLink (format "../../../css/%s/baseCSS.css" (format-time-string 
"%Y")))
  (setq dailyCSSLink (format "../../../css/%s/DailyCSS%s%s.css" 
(format-time-string "%Y") (format-time-string "%m") myDate))
  (setq previousDay (- myDate 1))
  (setq previousDate (format "%s%s" (format-time-string "%m") previousDay))
  (setq previousDayLink (format "../../%s/%s/index.html" (format-time-string 
"%m") previousDay))
  (setq nextDay (+ myDate 1))
  (setq nextDate (format "%s%s" (format-time-string "%m") nextDay))
  (setq nextDayLink (format "../../%s/%s/index.html" (format-time-string "%m") 
nextDay))
  (setq todayDate (format "%s/%s/%s" (format-time-string "%Y") 
(format-time-string "%m") myDate))
  (setq todayTemplate
        (format "<html>
    <head>
        <title>%s</title>
        <link rel=\"stylesheet\" type=\"text/css\" href=\"%s\" 
class=\"baseCSS\"/>
        <link rel=\"stylesheet\" type=\"text/css\" href=\"%s\" 
class=\"dailyCSS\"/>
    </head>
    <body>
        We're not there yet...
        <p class=\"navigation\">
            <a href=\"%s\" hreflang=\"en\" rel=\"prev\">%s</a>
            <a href=\"../../../index.html\" hreflang=\"en\">index</a>
            <a href=\"%s\" hreflang=\"en\" rel=\"next\">%s</a>
        </p> 
        <p>%s, %s </p>
        <p>
        <h1>%s</h1>
        <h2>%s</h2>     

        <p class=\"navigation\">
            <a href=\"%s\" hreflang=\"en\" rel=\"prev\">%s</a>
            <a href=\"../../../index.html\" hreflang=\"en\">index</a>
            <a href=\"%s\" hreflang=\"en\" rel=\"next\">&s</a>
        </p>
    </body>
</html>"
                "titre" baseCSSLink dailyCSSLink previousDayLink previousDate 
nextDayLink nextDate todayDate "..." "titre" "sous-titre" previousDayLink 
previousDate nextDayLink nextDate todayDate))

(write-region (dailyIndex) nil "~/Desktop/index.html"))

When run interactively, I always get a "wrong number of arguments" error. When 
I evaluate the internal expressions one by one, I never get this. I have no 
idea what is going on...
