Conflict between jQuery JavaScript Library versions v1.3.2 and v1.4.2

Hi,

I am using  jQuery JavaScript Library v1.3.2 for jquery calendar .

After that i added v1.4.2 for lightbox,Then calendar part is not working at all.

If i remove v1.4.2 the lightbox thing is not working.In that case calendar is working fine.Please help me to sort it out.
