• ## 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.

• ## 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…

• ## 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.

• ## Auotnumber and Text in calculated text

Can anyone please explain why this calculated text field formula works when Historic Order Number has a value but not when it's blank. I'm guessing it's something to do with the fact that Historic Order number is a text field whereas Order Number is an autonumber, however I can't find a to string function.

IF({Factory}="Toplink", "TLKNZ", IF({Factory}="Playmore", "PKNZ", IF({Factory}="Colaro", "CKNZ", IF({Factory}="Vithal", "VKNZ", "")))) & IF({Historic Order Number}="", {Order Number}, {Historic Order Number})

• ## Calculating Duration of Time

Is there a way to calculate Time, (not Base-10 numbers)?

I have a user who tracks Total Run Time (TRT) for TV Programming, and we need to sum/add the durations of multiple TRT's in the format of HH:MM:SS (Base 60).

• ## Use Regular Expression in Contains() or Snip()

It would be really great to be able to match a pattern of text with regular expression in contains() and snip()

If you use IF(contains("gmail",{url}),"Gmail","other")

It will return gmail for both because both contain gmail even though I am only looking for /account/gmail.

If I wanted to just find the account number (in this example) I could use something like /(\d+\w+)/g

• ## IS IT POSSIBLE TO COMBINE A NUMERIC FIELD AND A TEXT FIELD INTO A SINGLE CALCULATED FIELD

HAVE AN AUTOMATED NUMBER FIELD WITH A UNIQUE NUMBER FOR EACH RECORD, AND ANOTHER TEXT FIELD FOR LAST NAME. COMBINE THE TWO INTO ONE RECORD ID FIELD THAT CONTAINS THE NUMBER AND THE LAST NAME FOR EASIER IDENTIFICATION. I AM NEW TO THIS AND DID NOT SEE ANYTHING EXPLAINING WHETHER THIS COULD BE DONE IN THE KNOWLEDGEBASE

• ## I need to copy an auto-generated numeric ID to a text field if a condition is met

I have a checkbox in a table to deliniate a category: checked or not checked. If not checked, the record is an asset without a serial number. When not checked, I need TrackVia to copy the auto-generated numeric field (unique ID) for that record to a text field as a substitute for the serial number.
