I'm wanting to add together values from multiple fields in shp file and display the result as a the label here's what I'm looking at right now:

if ( [SwineGesBo] + [SwineSowLt] > 0) then output = output & [SwineGesBo] + [SwineSowLt] & "Sows"

Unfortunately what I've wrote here only sticks the two value together and does not sum them together. Is what I'm wanting to do possible? And if so how whould I do it? TIA

In addition to the below comments, I believe your if statement might give you incorrect results. Try putting the ">0" outside the parentheses. – Fezter Jan 17 '13 at 23:07

From the Help button on the Label Expression dialog:

Field values are automatically cast to text strings. Therefore, if you wish to use a numeric value in an arithmetic operation, or when making a comparison, you will need to cast it back to a numeric data type.

In place of

[SwineGesBo] + [SwineSowLt]

try using

cint([SwineGesBo]) + cint([SwineSowLt])

Thanks! That works – Seth_ia Jan 18 '13 at 14:00

Add and calculate a new field with the values summed, then call on this new field in the label expression.

Ok the concept makes sense to me. Could you give me an example of what this might look like? TIA – Seth_ia Jan 17 '13 at 21:00
