Calculated field with lookup does not update on edit

Hi,

Is Recalculate formula on Edit Mode set to "Yes"?

yes it is, since this is in repeated section

Can you send me the form please?

I am a armature, Please explain in detail, should I download the from and send it or is there  another way

Yes download and send on my email 

try enclose FmlHiddenCoulmnForItem with apostrophees (or even better with {textStart}{TextEnd}) as well.

minus sign might be interpreted as arithmetic operation and so cause problems.

Thanks, I tried Giving the formula as advised but the result is negative.  lookup("PriceListMultiplier","ColumnForLookup",{TextStart}FmlHiddenCoulmnForItem{TextEnd},"Multi"). As specified earlier while creating a new record the calculation is correct but while I try to edit a saved record the calculation fails What I had observed is that while opening on edit mode the value appears for a split second and the field recalculates and produces blank. I did try to set the recalculate on edit to No. but this also did not help. My feeling is that the recalculation happens before the concatenated string is generated and if a delay can be given to the recalculation it should work. Please advise If my assumption is right, if so how will I create a delay before the field recalculation.

that was my next question to ask - do you have recalculate on edit set for FmlHiddenCoulmnForItem as well?

if so, check developer console for any errors reported.
