Also, make sure you're saving and/or previewing the form as a "Dynamic" form not Static.

Thank you! I was able to get it to work using if (!nfPayment.isNull)

jasotastic -I really appreciate your help on this. It's exactly what I was looking for...! I was using a different script that worked for the most part, but it failed to update the Cumulative total whenever the user changed a payment amount. Your script does update the total, so I'm a very happy camper.The only thing I wonder is if it's possible to not show the Total value(s) on subsequent rows if no payment amount has been entered on active row (null) and/or if the payment field is blank on tha...

Sonia - private message me and I will help you.

Have you tried using a regular text field labeled "Signature", making the field protected, then saving as a Static PDF (provided it doesn't need to be Dynamic). Then you can use the Pencil tool (under Comments) to "scribble a signature". You probably know this already, but if the form will be completed by Reader users, you'll need to make it Reader Enabled.Also, since the signature will be applied as a "Comment," you may want to "print to PDF" to flatten the form once the signature is obtained.N...

Lastly, you might already know this, but also make sure you are referencing the correct paths in your scripts. For example, if your images are placed in another/separate subform called Photos, then the above path is incorrect.Instead, it would be something like:if (this.rawValue == "1"){Photos.Image1.presence ="visible"Photos.Image2.presence = "hidden"Photos.Image3.presence = "hidden"}if (this.rawValue == "2"){Photos.Image1.presence = "hidden"Photos.Image2.presence = "visible"Photos.Image3.prese...

Re: the difference between the Image and Image Field objects... The "Image" object is typically used during design (i.e. the image is added to the form by the form designer - just like what you are doing by pre-placing the image son the form ). If you want the image to be available for future edits (especially when editing on a different machine) then you'd want to select the "Embed Image Date" option. Doing this will increase the overall file size, but it help ensure the graphic will be there i...

P.S. In the solution above, the images reside in the form - you are basically controlling the "presence"...either "hidden" or "visible". This is with the presumption that only one image is visible at a time. You will have to determine where the images are placed on the form (i.e. stacked on top of one another, within a subform, etc).

NOTE: Below are two simple options. Assign an exported value to the selectable items in the drop-down (i.e. 1,2,3). You would do this on the Binding tab (Specify Item Values)OPTION 1:Use the following script on the "Exit" event of the drop-downif (this.rawValue == "1"){//a "space" character to represent a blank option in the drop-downImage1.presence = "hidden"Image2.presence = "hidden"}if (this.rawValue == "2"){Image1.presence = "visible"Image2.presence = "hidden"}if (this.rawValue == "3"){Image...
