Counting number of days in Forms

Hi, I'm new to Designer, and I use the Forms part only. I'm looking for how to have a Numeric Field show a calculation of days. The form has two date/time fields and I want my Numeric Field to show how many days.

 

I'm reading through the FormCalc and am having a lot of trouble. Thank you to anyone that can help. 🙂

Hi,

 

Assuming you already have 2(DateField1 & DateField2) date fields and a num(DaysDifference) field,

 

- Navigate to the Exit event of DateField2 (or use the Calculate event of DaysDifference).

- Select FormCalc for Scripting language

 

if (DateField1.rawValue ne null and DateField2.rawValue ne null) then DaysDifference.rawValue = Date2Num(DateField1, "YYYY-MM-DD") - Date2Num(DateField2, "YYYY-MM-DD") else DaysDifference.rawValue = "" endif

 

PS: you may need to maintain same format as of code. Alternatively, you can make relevant changes in code.

 

Hope this helps.

 

Kind regards,

Kiran Buthpur

      hi @dominiquelo1 

      The overall approach is valid — it checks if both date fields have values and calculates the difference using Date2Num(). However, it throws an error because rawValue is being accessed on unknown or incorrect field names.

      Suggested Fix:

      • Confirm that the field names (DateField1, DateField2, DaysDifference) match exactly in the form.
      • Use the Calculate event of the DaysDifference numeric field (rather than Exit), as it automatically updates when either date changes.
      • Use HasValue() and formattedValue to safely reference date fields.
      if (HasValue(DateField1) and HasValue(DateField2)) then Date2Num(DateField2.formattedValue, "YYYY-MM-DD") - Date2Num(DateField1.formattedValue, "YYYY-MM-DD") else "" endif

       Regards,

      Karishma.
