Velocity - Display specific value

[Travis_Schwartz]

So I have this code:

#if( $lead.autoPreApprovalNewRate.toString().equals("") )
#set( $lead.autoPreApprovalNewRate = 0 )
$number.number( $math.sub($lead.autoPreApprovalNewRate, "1") )
#end

And when there is a value in the

$lead.autoPreApprovalNewRate

field, this works beautifully. The problem is if they don't have a value, the programing makes sure it's a 0, and the subtraction turns it into -1. I'm sure there is just another #if #else... I'm just not able to figure it out.

Thanks.

Lot of confusing stuff here, and it’s just a few lines of code. 🙂

1. autoPreApprovalNewRate must already be an empty String, so it doesn’t need toString()
2. it can’t really be working beautifully, because everything is wrapped in the same condition
3. the second argument to $math.sub should be a Number, you’re just lucky that it’s converting the constant “1" to 1 
4. $math.sub already converts the result to a Number instance

If your requirement is

• if autoPreApprovalNewRate is the empty string, set the effective rate to 0
• else set the effective rate to (autoPreApprovalNewRate - 1)

then that's

#if( $lead.autoPreApprovalNewRate.equals("") )
#set( $outputRate = 0 )
#else
#set( $outputRate = $math.sub($lead.autoPreApprovalNewRate, 1) )
#end
${outputRate}
