**Nolasol**Hello,

I think the available calculations and conditions are very important and great parts of JotForm's system.

I think it would be more good to be able build a condition in the calculation field directly as a mathematical expression.

Then I would be able to build a complex condition, including both AND and OR function in one formula (now I have to build conditions separated if contains AND and OR functions to same field).

Now it's impossible because calculation field doesn't allow to insert '=', '<', '>' etc. symbols.For example a calculation in "TOTAL AMOUNT" field :

((DEP_COUNTRY_FIELD = "Spain") * (LINECODE_FIELD = 3) * (DEP_SPAINTOWN3)) + ((DEP_COUNTRY_FIELD = "Spain") * (LINECODE_FIELD = 1) * (DEP_SPAINTOWN1))

(

*Yes, I know, this equation is not optimal and would be more simplified but I need to you understand what I would like to show you!)*In this example if user selects 'Spain' as departure country and then selects a bus line No. 3, then she/he has to pay the calculation value of 'DEP_SPAINTOWN3'.

If the user selects 'Spain' as departure country and then selects the bus line No. 1 (it's a different line with different ticket prices), she/he has to pay the calculation value of 'DEP_SPAINTOWN1'.Now I have to build two separated conditions for updating the value of 'TOTAL AMOUNT', first condition is "IF SPAIN and IF LINE 3, then SPAINTOWN3", and a next one is "IF SPAIN and IF LINE=1 then SPAINTOWN1" and I think it's more difficult and not optimal.

Even if I have more parent fields and more conditions, then actual solution is much more difficult and would be simplified by a mathematical 'construction'.I need so much this option... :-)

Thanks

**Welvin**Hi Noemi,

Are you suggesting to add the conditional logic option directly into the widget without using this method: http://www.jotform.com/help/268-How-to-Insert-Text-or-Mathematical-Caculation-into-a-field-using-a-Condition? Unfortunately, I'm not sure if that would be possible. For now, I would suggest adding conditional logic for each value that you want to insert into a field. I know that you have a few more options into your form as you've mentioned to your previous thread, but the conditional logic should also work.

Or maybe, you can show the calculation fields and use "

**Ignore Hidden Fields**" method? Then we'll try to hide it using custom CSS codes? How's that?Thanks

**Nolasol**Hi Welvin again :-) ,

yes, you understand me..

OK, I will use conditional logic with separated lines for every conditions (I feel it would be more comfortable with a new option to use mathematical algorhytm to use as condition.)

Yes, I found a solution to use "Ignore hidden fields" in a calculation.

If I don't use any mathematical symbol (+, * etc.), only a list of included dropdown lists, then calculation works correctly and values of hidden dropdowns are disappearing from calculation :-)You can check result already in my form (#input_126, name: calc_inddij and then #input_105, name: indcimdij, label: "Címreállási díj" fields).

Thanks for your help!
