Please help me solve this problem

Hello All,
I am new to crystalreport am using crystalreport 8.5. I have to provide the link for
a column whose value is > 1000. i don't want to suppress the values other than1000.
My Problem is the link should be enabled only when the value is > 1000. Please share your experience to solve this problem.
Thanks in advance
