APEX_ITEM.TEXT and solution for enabling and dispabling a button

Question

Hi All,
Please let me know how can we have a format mask for an Item created using apex_item.text.
I would like to add a Number format mask with three decimals in this report column
APEX_ITEM.TEXT (2, INV_VALUE, 15, 20, 'readonly=readonly style=""')
Also do let me know the following points based on the followup to this link:
Use of Checkbox in Report for calculation and determine checked records
1. How can I enable or disable a button based on value of a Page Item being > 0, this also should be done when a check box is checked or unchecked.
2. One more clarification about adding the total depending upon check box checked or unchecked.
On checking and un-checking the total gets added and subtracted as required, but I have noticed that the the session values of the Item for Total is not as the one displayed. Why is it so. Please guide.
Thanks & regards

Hi Vee,
Thanks for the reply.
document.getElementById(...)' is null or not an objectCheck if the button is rendered with id="PAY_DUES"+ or not. You can view the HTML source code of the button and see if it has such an id or not. The source code is as follows:
<a href="javascript:popUp2('f?p=1002:23:3713834878987986::NO::P23_INVOICES,P23_RCP_AMOUNT_PAID:,0', 320, 450)" class="t20Button">Pay Dues</a>
Else add an id attribute to the button in button attributes(ensure that you have the BUTTON_ATTRIBUTES substitution string used in the button template)Template of button is as follows and the Substitution String #BUTTON_ATTRIBUTES# is not Referenced.
<a href="#LINK#" class="t20Button">#LABEL#</a>
but I have noticed that the the session values of the Item for Total is not as the one displayedThe session value of the item is usually set when you submit the page or use an ajax process/ Dynamic Action to set it. If you this is required , set the item's session state calling a dummy/null ondemand process or a dummy PLSQL dynamic Action using the item name in the "List of items to Submit" field.This issue is resolved for me in other thread.
