Adobe PDF prohibit unchecking of check box

[MContri]

I have an Interactive PDF form. On this form I have a small group (7 options)of checkboxes. 2 of the boxes are directly associated with each other (one way relationship)

These 2 checkboxes are Network and Infrastructure (dependent upon Network).

The scenarion is the following:

• If Network is checked then Infrastructure needs to be checked as well. (This part is complete)
• If user tries to unchecked Infrastructure, then they will not be able to unchecked it without first unchecking Network, but I want to explain to them why, think alert or something. ( this i am having problems with)
• Infrastructure can be toggled on/off any other time Network is not checked. Got this covered)

I currently am using the following script on Mouse Up:

 Var f = this.getField("cr_infrastructure");

If (event.target.isBoxChecked(0,true))

{ f.checkThisBox(0,true);}

Else

{f.checkThisBox(0,false);}

That script will not work, it should be 'var', 'else', 'if' not 'Var', 'Else', 'If' it's case sensitive.

To do what you want, you will need to have custom calculation script placed in any text field.

What is the exact name of Network checkbox?

Nit sure what you mean by not gonna work. I have the order just like you stated and Actually the script does work for checking and unchecking the Infrastructure check box when the Network check box is clicked and unclicked. 

I have never done a calculated script before and the name of the Network checkbox is cr_Network.

The issue is not the order but the spelling. It's "var" not "Var", "if" not "If", etc. Your code as you posted it will produce multiple error messages. I assume that's not really your code, or it wouldn't work at all. It was probably modified when you copied it to something like Word before posting it here.

Oh I understand what you are getting at. You are correct that isn't my exact code. I typed it using my phone. The code I have is in correct lowercase

[Nesa Nurani]

If you have in your script 'var', else', 'if' it will work but script you posted will not work.

Use this as 'Mouse UP' action of "cr_infrastructure" checkbox:

var net = this.getField("cr_Network");
if(net.isBoxChecked(0)){
app.alert("Please uncheck Network checkbox first.",3);
event.target.checkThisBox(0);}
