Request change over value or text of option

I’m having a problem with dhtmlxform. When I execute a send(), the values of the request aren’t consistent. Once it sends the value of the option selected in combo, under same circunstances, other request sends the text of the option. For example

Request for Execution 1:

back 0 == Value
colorPrint 0 == Value
coverPage 0 == Value
dimensionsLarge
dividerSheet 0
finition 0
finitionLarge 0
finitionType
finitionTypeLarge
format 6
formatLarge
large 0
name r
numberDivider
reliureGauche null
reliureGaucheLarge null
support 80 gr Blanc == Text
supportLarge
templateId
type 21
typeRv catalog.duplex.doubleBook

Request for execution 2:

back Aucun == Text
colorPrint 0 == Value
coverPage Aucun == Text
dimensionsLarge
dividerSheet 0
finition 0
finitionLarge 0
finitionType
finitionTypeLarge
format 6
formatLarge
large 0
name g
numberDivider
reliureGauche null
reliureGaucheLarge null
support 80 gr Blanc
supportLarge
templateId
type 21
typeRv catalog.duplex.doubleBook

I don’t know if you can see the problem, but it doesn’t send always the value or the text, it is some kind of random behaviour.

The problem began after I changed the dhtmlxform.js for a version Andrei from dhtmlx.com provided me that solved another problem.

If you need further information, please ask me about it.

I hope you can help me.

Thanks
