**escarecard**I'm trying to calculate a series of inputs with predefined inputs of 0-12. When calculating, the form seems to see 0 as 1, 1 as 2 even though the calculation values are set as 0-12.

Is the form calculation unable to recognise a zero value?

Thanks!

*This is a re-post of a comment on How to Perform Form Calculation Using a Widget***Sammy**If i may ask what type of calculations are you performing and also which form element are you using to hold your predefined values.

Also you can check that the inputs in the from are set to numerical values and not alphanumeric.

To do this open the calculation form wizard by clicking on the

**wand**buttonMakes sure the value type for the fields reads

**0-9**and not**a-z**save the changes and then try your calculation again.**escarecard**Hi Sammy

I've checked the above and all seems correct. The values are in a Drop Down form element and are 0-12 and in the calculation field it's basic addition. The calculation seems to be taking the zero value as a 1 and so forth.

Thanks

**escarecard**Hi - there appears to have been a problem with the initial field that was screwing up the calculation. I've deleted it and it's fine now. Thanks for your help...
