1. ## is blank

Hi,

I am trying to create a formula where I have 2 is blank conditions and 3 outcomes (terminology may not be right here).

I can get the formula to work if I only have 2 outcomes, but as soon as I add the 3rd I get the following message "Too many arguments to function 'IF'. Expected 3 but got 4." I am not sure how to rectify this.

This is what I am trying to do:
if(and(isBlank({Handover Commit Month}),isBlank({Projected Handover KPI})),dateadd({BD - TECH HO},182,"d"),{Projected Handover KPI},{Handover Commit Month})

I want to say if Handover Commit is blank then use…

4. ## Count working hours

I need to count working hours in the range defined by "Start" and "End" fields. Both fields are Date and Time format. The working day lasts from 7 AM till 3:30 PM. I need to count time only from this range. Overtime and weekends should not be included. I can start and end work any day at any time.
weekdays() function counts only days, datedif() function includes all 24 hours and weekends.
Any ideas?

5. ## sum a specific column when the child record is in a specific location

I have a table where users can select a parent record in more than one location. For example, a child table, "work order" contains both "Service 1", and "Service 2" links to the "services" table. Each linked service has an associated quantity column in the "work order" table. I have tried using the sum function in the "services" table to sum the total services entered but when I sum the "service 1 quantity" all of the values in that column are added regardless of whether the service was a parent record in the "service 1" link or in the "service…

6. ## Calculating Task Completion Time

I am looking for a way to capture how long it takes a user to create a record.
Does TrackVia stamp when a Form is opened? If so, then I can use this value in a datedif formula against the record Create Date/Time to see how long it took to open the form, key in the information, and click Save.

In most languages you can add comments that does not affect the code or formula. Out of habit I tried to use ' but that didn't seem to work. Does trackvia allow for this kind of thing and if so what is the symbol or text?

E.g.

If({Field} = 1, A + B, A + C)

16. ## How do I calculate the sum of a column so that I can then use that to determine the percentage of the total for a given value?

For example I want to show the percentage of total sales by store, salesperson etc.
Everything I have tried so far just returns 100% as it is only doing the calculation on a row by row basis rather than using the column total.

20. ## Is there a maximum number of IF statements I can nest?

I ask this because when I go to save the calculated field a dialog box appears stating: "We've had a minor problem. We can't tell if your request completed. Please click OK below to refresh your browser." Prior to this dialog box appearing, however, a string of text appears (stating: "Large tables usually save in under a minute. Feel free to leave this page, we'll let you know when this is saved") atop the whited out page as the calculated field is saved - see attachment "Problem with IF Statement."

Also, once I paste the copied IF statement formula into…
