Scan through object list when named using [ ] - Please help!

[southbeach]

I am using PHP to dynamically generate forms with hidden values. I am using names such as isBD[], isHZ[], isOV[], etc. The reason behind the naming convention is so that PHP can process the fields as arrays when form is submitted.

The form I am working on is a data grid with a single check box field per row. If a check box is clicked, I am calling

	function clicked(n)
	{
		isBD=document.forms[0].isBD;
		isHZ=document.forms[0].isHZ;
		isOV=document.forms[0].isOV;
		isFUM=document.forms[0].isFUM;
		pcs=document.forms[0].pcs;
		wgt=document.forms[0].wgt;
		vwgt=document.forms[0].vwgt;
		povalue=document.forms[0].povalue;
		ship=document.forms[0].ship;
		totalPCS=document.getElementById('totalPCSID').value;
		totalKGS=document.getElementById('totalKGSID').value;
		totalVKGS=document.getElementById('totalVKGSID').value;
		totalVAL=document.getElementById('totalVALID').value;
		bdPCS=document.getElementById('bdPCSID').value;
		ovPCS=document.getElementById('ovPCSID').value;
		fumPCS=document.getElementById('hzPCSID').value;
		hazPCS=document.getElementById('fumPCSID').value;
		if (ship[n].checked == true) {
			totalPCS=(1*totalPCS)+(1*ship[n].value);
			totalKGS=(1*totalKGS)+(1*wgt[n].value);
			totalVKGS=(1*totalVKGS)+(1*vwgt[n].value);
			totalVAL=(1*totalVAL)+(1*povalue[n].value);
			if (isBD[n].value == 'Y' || isBD[n].value == 'y') bdPCS=(1*bdPCS)+(1*ship[n].value);
			if (isHZ[n].value == 'Y' || isHZ[n].value == 'y') hzPCS=(1*hzPCS)+(1*ship[n].value);
			if (isOV[n].value == 'Y' || isOV[n].value == 'y') ovPCS=(1*ovPCS)+(1*ship[n].value);
			if (fumBD[n].value == 'Y' || fumBD[n].value == 'y') fumPCS=(1*fumPCS)+(1*ship[n].value);			
		} else {
			totalPCS=(1*totalPCS)-(1*ship[n].value);
			totalKGS=(1*totalKGS)-(1*wgt[n].value);
			totalVKGS=(1*totalVKGS)-(1*vwgt[n].value);
			totalVAL=(1*totalVAL)-(1*povalue[n].value);
			if (isBD[n].value == 'Y' || isBD[n].value == 'y') bdPCS=(1*bdPCS)-(1*ship[n].value);
			if (isHZ[n].value == 'Y' || isHZ[n].value == 'y') hzPCS=(1*hzPCS)-(1*ship[n].value);
			if (isOV[n].value == 'Y' || isOV[n].value == 'y') ovPCS=(1*ovPCS)-(1*ship[n].value);
			if (fumBD[n].value == 'Y' || fumBD[n].value == 'y') fumPCS=(1*fumPCS)-(1*ship[n].value);					
		}
		document.getElementById('totalPCSID').value=totalPCS;
		document.getElementById('totalKGSID').value=totalKGS;
		document.getElementById('totalVKGSID').value=totalVKGS;
		document.getElementById('totalVALID').value=totalVAL;
		document.getElementById('bdPCSID').value=bdPCS;
		document.getElementById('ovPCSID').value=ovPCS;
		document.getElementById('hzPCSID').value=hzPCS;
		document.getElementById('fumPCSID').value=fumPCS;
		xajax_clicked(totalPCS,totalKGS,totalVKGS,totalVAL,bdPCS,ovPCS,hzPCS,fumPCS);
	}

which in turn should check the values of associated array elements and set accumulative values accordingly.

I am getting errors on the line

if (ship[n].checked == true) {

The error tells me that "ship" is not defined. The error is correct since I named the fields "ship[]" not "ship".

What must I do to get around this problem? I mean, short of having a second set of fields excluding the square brackets.

Thank you all in advance for your assistance!
