Re: Variables - Integer vs. Character

Why don't you use parseInt()? There you go:

totalCost = base;
totalCost += parseInt(document.forms[0].motherboard_cost.value);
totalCost += parseInt(document.forms[0].hard_drive_cost.value);
totalCost += parseInt(document.forms[0].windows_software_cost.value);
totalCost += parseInt(document.forms[0].monitor_speakers_cost.value);
totalCost += parseInt(document.forms[0].sdram_cost.value);
totalCost += parseInt(document.forms[0].software_suite_cost.value);
document.forms[0].total.value = totalCost;

HTH,
