[TYPO3-project-formidable] majix, how to combine multiple clientData values

[Alexander Rose]

Hi all,

first of all: thanks for this great extension!

I would like to multiply the values of two input fields field_a and  
field_b and put the result into field_c when some onclick event occurs.

something naiv like

$this->aORenderlets["field_c"]->majixSetHtml("clientData::field_a *  
clientData::field_b")

does not work...

is there any way to do this within the formidable framework?

thanks in advance

alex
