Conditional Display

I'm trying to display {calculation-18} when {calculation-4} is less than or equal to 999.5; and {calculation-4} when it's greater than 999.5.

[e2pdf-if][e2pdf-if-condition]{calculation-4}[<=]999.5[/e2pdf-if-condition][e2pdf-if-do]
<b>${calculation-18}</b>[/e2pdf-if-do][e2pdf-if-else]<b>${calculation-4}</b>[/e2pdf-if-else][/e2pdf-if]

Right now, it's always displaying the else condition. It works as expected when I replace {calculation-4} with 1000 in the condition. Can you see anything wrong with what I have?

Also, [<=] is replaced by [&lt;=], but I don't understand why ... ? It's not replaced in another snippet of code I have elsewhere.

My feeling is that {calculation-4} is displaying as a string instead of a number ... ?

I created a 'test form' with this code:

<p>[e2pdf-if][e2pdf-if-condition]{calculation-4}[<=]999.5[/e2pdf-if-condition][e2pdf-if-do]
<b>${calculation-18}</b>[/e2pdf-if-do][e2pdf-if-else]<b>${calculation-4}</b>[/e2pdf-if-else][/e2pdf-if]</p>
<br>
<p>${calculation-4}</p>

I've attached the output.

In this example, {calculation-4} = 23,990.00, which is not [<=] 999.5 so the else condition should be triggered and {calculation-4} should be displayed. As you can see in the attachment, {calculation-18} is being displayed, meaning that the if condition is being triggered.

[In my original question, I stated it was always displaying the else value. However, I meant the opposite: it is always displaying the *if* value.]

<p>[e2pdf-if][e2pdf-if-condition]{calculation-4}[>=]999.5[/e2pdf-if-condition][e2pdf-if-do]
<b>${calculation-18}</b>[/e2pdf-if-do][e2pdf-if-else]<b>${calculation-4}</b>[/e2pdf-if-else][/e2pdf-if]</p>

I switch t he [<=] to [>=] and now it's always displaying the else value (I've used datasets where {calcuation-4} is greater than 999.5 as in the example above and also datasets where {calculation-4} is less than 999.5. Both produce the same output. It's always reading it as a number less than 999.5.

That worked! Thank you!
