If you are using a CreateScript then the property used in ReadOnly.

oppo_closed.ReadOnly = true;

Hi Jeff,

Thank you for the reply.

I should have put all the scripts I tested, the problem I am having is checking the value of the date field.

The last script I tested sets readonly when the date is entered and when the date is blank

var dOppoClosed="";

dOppoClosed = new String(Values("oppo_closed"));

if(dOppoClosed=="null" || dOppoClosed=="Undefined")

{

ReadOnly=false;

}

else

{

ReadOnly=true;

}

The IF statement that checks the date does not appear to work with a date field for any of my scripts,

The readonly statement is working and I have manage to get DISABLE To work as well

Problem still remains the check on date value, it is always seen as CONTAINS A VALUE

It’s a bit of an *** about face way of doing it but you could just look straight at the underlying data and do so something like:

var oppId = CRM.GetContextInfo(“Opportunity”, “oppo_opportunityid”);

var oppRec = CRM.FindRecord(“Opportunity”, “oppo_opportunityid = “ + oppId + “ and oppo_closed is null");

//if recordcount is 0, there must be an oppo_closed value so make it readonly

if (oppRec.RecordCount == 0)

ReadOnly =false;

else

ReadOnly=true;

Just noticed my true and false is the wrong way around in the IF statement .... it's still early!

Thank you Peter!

This solved worked perfectly (readOnly adjustment included)

Greatly appreciated
