Microsoft JScript Error

Hi everyone I have an issue that deals with javascript and XSL. I get the following error:

Microsoft JScript runtime error 'document' is undefined line = 23, col =2(line is offset from the start of the script block). Error returned from property or method call.

Now I use two html controls: a hidden html control and button html control. The hidden html control value is being set when the page is loaded and the button html control has a xsl if statement that uses an expr attribute to call a funciton that will evaluate the hiddent control value. The function return the value retrieve from the hiddend html control.

Here is my code:

if (RoleIdVal == "Global View") { document.getElementById("cc_role_id").value = 1; } else { document.getElementById("cc_role_id").value = 0; }

cc_role_id is my hidden control.

Here the structure on the xsl page:

<inputtype="hidden"id="cc_role_id"/>

<buttononclick="addFile()">

<xsl:ifexpr="CheckTest() == 1">

<xsl:attributename="disabled">true</xsl:attribute>

</xsl:if>

</button>

Here is the CheckTest function that retuns a value:
