IF Statement

Dude

Being very new to programming I am struggling with writing the conditional logic for a simple IF statement.

I have a stylesheet switcher which stores the users style preference in a cookie. I am having a problem if the user has not been to the site before or cleared there cookies. In this instance I would like to default to styles.css.

Session("stylesheet")=request.Cookies("stylesheet")
if request.QueryString("stylesheet") = "styles" then
Session("stylesheet")="styles.css"
elseif request.QueryString("stylesheet") = "blackonwhite" then
Session("stylesheet")="blackonwhite.css"
else
Session("stylesheet")="styles.css"
end if

It is much better if you have the key words IF, ELSE, END IF in CAPS that way you can see it better.

also indent the code so you can see which bit is with what (not sure if its the forum thats missed out the indentation.)

looking at your code you could simplfy your conditions to this

IF requested style <> blackonwhite  THEN
   set style to standard style
ELSE
  set style to blackonwhite
END IF

the above is not the real code just the idea.

No gap between "else" and "if". Two IF's and only one ENDIF.

It's good practise to use CAPS for reserved words and to indent, as per the above, as it makes debugging easier.

HTH.

I don't know which languauge this is, but one ENDIF is correct if it supports ELSEIF:

IF ... THEN

ELSEIF .... THEN

ELSE

ENDIF

Otherwise it would be clearer as:

IF ... THEN

ELSE

IF ... THEN

ELSE

END IF

END IF
