Hi

I have to scripts in my app.

The fisrt one, runs just fine.

The second, simply ignores the first "if" hipoteses.

the code is below:

$(document).on('knack-view-render.view\_20', function(event, view, data) {

&nbsp; &nbsp;

&nbsp; &nbsp; $("#view\_20 td.field\_2").each(function() {

&nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; var textColor = ($(this).find("span").text().trim() == "Não") ? "#ff0000" : "#1c631f"; // #ff0000 is red and the #1c631f is green

&nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; $(this).css("color", textColor);

&nbsp; &nbsp;

&nbsp; &nbsp; })

&nbsp;

});

$(document).on('knack-view-render.view\_20', function(event, view, data) {

&nbsp; &nbsp;

&nbsp; &nbsp; $("#view\_20 td.field\_4").each(function() {

&nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; if (parseInt($(this).val(), 10) \> 50) {

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;$(this).css('color', 'red');

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;alert("deu certo");

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else {

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;$(this).css('color', 'blue');

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;var texto = ("deu errado" );

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;alert(texto); } // #ff0000 is red and the #1c631f is green

&nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;

&nbsp; &nbsp;

&nbsp; &nbsp; });

&nbsp;

});

The alert is only designed to check the if conditions.

Thanks for any help.

I think that means your parseInt function was passed something that was NotANumber.

So $(this).val() is not a parseable number. &nbsp;If you're sure it should be - that probably means $(this) isn't pointing at what you think it is.

You could next try a console.log($(this)); and make sure you are looking at the proper element.

Thanks Richard

I tried and got a NaN output in the Console.

I'm assuming by ignoring, you're saying you are either always getting cells that are blue OR red? &nbsp;If so,

If it were me, I'd put a console.log(parseInt($(this).val(), 10)); above the if call and see if you're getting what you think you should be before doing anything else.
