"Inline scripting" is witchcraft to me..
I know I use/need it all the time but it's borrowed clothes.
Snippets picked up here and there - slightly modified to fit in
different contexts.
I need somebodys help whenever I want sth that isn't "prepacked" and
available as a plugin already..
I really like to accomplish things by trial and error - Many of Erics
plugins lend themselves to this kind of investigation.
When I play around with javascript or try to combine scripts I never
succeed.
I am most comfortable with variables and the ability to replace bits
and pieces without worrying if it's a comma, a linebreak or some other
triviality which breaks the code..
If it's ok with you - it's ok with me..

It seems that this code doesn't a student(slice) with John in the
tiddler titled Student - it should output: "No such student" if John
is missing... However I get an errormessage if the John slice is
missing and the same is true if I make the slice and don't define a
value. It doesen't seem to solve the problem...
I choose to do this (I'm using custom fieldvalues instead of slices
and I use Erics wikiCalc script - modified for my special case ECTS
transcribed into the Danish gradesystem):
tiddler title: [[WikiCalcScript]]
<script>
var g=store.getValue("$1","points");
return g<1?'-3' : g<25?'00' : g<37?'2' : g<48?'4' : g<59?'7' :
g<66?'10' : g<71?'12' : 'no points';
</script>
Then I made a template "wrapped in html"
<html><table><td align="center" valign="top"><b>Part A :</b><<tiddler
RefreshTiddler with: update>> </ td><tr><td><span class='editor'
macro='edit points'></span>points<br> grade = <<tiddler WikiCalcScript
with: {{tiddler.title}}>></html> (needs
http://www.tiddlytools.com/#HTMLFormattingPlugin)
And again in a new tiddler where it is one of several tabs:
<<tabs txt$1
'$1 Text' '$1 viewer Tab' [[$1]]
'Part A' '$1 DelA Tab' PartA
'Part B' '$1 DelB Tab' PartBbutton
'Part C ' '$1 DelC Tab' PartCbutton
'Total ' '$1 Total Tab' [[Simple form2]]
'All at once ' '$1 All Tab' [[AllHere]]
>>
And I've embedded it in the ViewTemplate. It is controlled by
HideWhenPlugin http://mptw.tiddlyspot.com/#HideWhenPlugin like this:
(one of the tabs is replacing the "normal viewer")
<div macro="hideWhenTaggedAny student">
<div class='viewer' macro='view text wikified'></div></div>
<div macro="showWhenTagged student"><div class='viewer' macro="tiddler
tabs with: {{tiddler.title}}"></div></div>
To be able to use the 'edit tiddler function' in the viewtiddler I
also installed Eric's EditFieldPlugin
http://www.tiddlytools.com/#EditFieldPlugin.
