I have 3 different text (html formula involved) fields that shows a calculated number of days a project sit on a certain stage. Now, I want to create a 4th field to show the total number of days a project sat by adding 3 fields/stages. Any input on how to do that?

There are three formula text fields which gives the number of days as output like

[Formula 1] = 12

[Formula 2] = 10

[Formula 3] = 14

On 4th field which is [Formula 4] , you need to add the 12+10+14 and show the sum as 36 in the last field .

Is this is what you are asking !!!
• 786 Points Yes, exactly John. I want the 4th field to say "36" as the answer going by your example.
• 312 Points If the 4th field is a Numeric Field:
toNumber([Formula 1] )+toNumber([Formula 2] )+toNumber([Formula 3] )

If the 4th field is a Text Field:
toText(toNumber([Formula 1] )+toNumber([Formula 2] )+toNumber([Formula 3] ))

• 786 Points Thanks Aiden. It is working on cases where there is a value on all 3 fields. If one of them is yet to come to pass (e.g., two stages are crossed with a delay and the third stage is yet to start), the 4th field (with the above formula) is not showing any result. Can it be fixed, even if the one of the 3 stages has "null/no/0" for a value? Sometimes, we do have cases where we skip a stage and move the project right into the next one, where, only 2 stages have applicable delays and the third one might not. Thanks for your help.
• 786 Points By the way, I used your "Text" field formula.
• 312 Points Please try below and let me know:
totext(
if ( [Formula 1] =  null or [Formula 1] = ""  , 0 , toNumber([Formula 1] )+if ( [Formula 2] =  null or [Formula 2] = ""  , 0 , toNumber([Formula 2] )+if ( [Formula 3] =  null or [Formula 3] = ""  , 0 , toNumber([Formula 3] )
)
• 786 Points What i meant by "null/no value/0" is that it is 'empty' - it did not have any text or number in those fields. Sorry, for the inconvenience caused.
• 312 Points The ( [Formula 1] = "" ) should filter those out.
