hide and show image fields based on value

[arshadsolehry]

I have two image fields and images are read only. I have a text field and I want to swop images based on values. If the value is 0 or less than 0 like - 1 image1 and if +1 or greater than +1 then image2.

Is this possible?

Sure. As the custom validation script of the text field enter the following:

this.getField("image1").display = (event.value<=0) ? display.visible : display.hidden;

this.getField("image2").display = (event.value>0) ? display.visible : display.hidden;

Really magic. Just one more question. If the value is 0 then both images should be hidden. Can you please modify code?

You can see that the condition on the first line of code is   event.value<=0  . This is read as "when the value is less than or equal to 0" .  When the codition is satisfied the display setting for the field is set to display.visible .  I think you can see how this works. If you want both images to be hidden, then the condition needs to be modified so that it is not true when the value is 0, i.e., remove the equals.
