basic coding in CR_v8

[2bRaistlin]

Hi i'm a total newbee to crystal report and some very basic stuff still isn't clear to me.

I created a new 'formula' (called"@check4null) and wanted to write this code:

shared zero as boolean

if ({caric.codana}) ="" then
zero = true
else
zero = false
end if

can someone explain me why i get a error message similar to "always have to assign a value to variable within the formula"?

i'm using CR v.8.0

Thank you so much! R.

When writing formulas using Basic Syntax you need to assign the return value of the formula via the special variable appropriately called Formula

shared zero as boolean

if ({caric.codana}) ="" then
zero = true
else
zero = false
end if

formula = zero
