Interesting, I wasn't aware of the setVariable() function. I've just always used <cfset &quot;var#x#&quot; = &quot;value#x#&quot;> to do this.

you have to evaluate(var i)
check in the docs for the exact syntax
but it should finally look like this : <cfif #evaluate(&quot;#..

 

[obouillaud]

<CFSET temp =&quot;#tabl_thema[arraylen(tabl_thema)][1]#&quot;>
<CFSET temp2 = #evaluate(&quot;#temp#&quot#>
<CFIF form.#temp2# EQ &quot;yes&quot;>#thematique# a été sélectionnée.</CFIF>

toute bidouille de quelque type que ce soit me renvoit une erreur.
form.une_variable ne veut jamais fonctionner !!!

-> essaie de faire un cfoutput de temps2 apres la 2eme ligne, tu dois avoir la bonne valeur dedans
-> dans la 3eme ligne, d'une c'est #form.temp2# et pas form.#temp2#; de deux temp2 tu l'as defini dans un cfset c'est donc sur qu'il vient pas d'une form !!!!!

for english users that might be interested in knowing more ;-)
-> temp2 after the 2nd line should be correct. <cfoutput>#temp2#</cfoutput> should display the correct value.
-> the problem(s) is(are) in the 3rd line :
* it's #form.temp2# or #temp2# but certainly not what is written !!
* what's more, temp2 does not come from a form (it has just been created on the above line) so you'll never ever get a value using form.temp2 !!!!
