Cant figure out this problem

[Karl Blessing]

I get this Error

[red]Runtime Error : Line 85 Object doesnt support this property or method[/red]

this is the line I get the error on.

cohort_year = document.TheForm.cohort_year.substring(0,cohortcheck)+ "%26" + document.TheForm.cohort_year.substring(cohortcheck+1,cohort_year.length);

TheForm is a Form, cohort_year is a <select...> box

anyone have any clue. [sig]<p>Karl<br><a href=mailto:kb244@kb244.com>kb244@kb244.com</a><br><a href=

I think you problem is that you are using the same name for you variable as your form name.

try this:

cohortYear = document.TheForm.cohort_year.substring(0,cohortcheck)+ &quot;%26&quot; + document.TheForm.cohortYear.substring(cohortcheck+1,cohortYear.length);

I think you're trying to use 'substring' on a non-text object. You need to identify the selected option within the select box, and the associated value:-

if (document.TheForm.cohort_year.options[i].selected) 
{
cohortYear = document.TheForm.cohort_year.options[i].text.substring(0,cohortcheck)+ "%26" + document.TheForm.cohortYear.options[i].text.substring(cohortcheck+1,document.TheForm.cohortYear.options[i].text.length);
}

I figured that out right before leaving work fatbloke, oh also it's selected, not &quot;selectedindex&quot;? cuz that might be another problem. [sig]<p>Karl<br><a href=mailto:kb244@kb244.com>kb244@kb244.com</a><br><a href=
