I am trying to select a check box for a corresponding text pattern in selenium IDE

Using regexp I can find the text but how can I select the box ?

I have tried the following but in vain

Open /
storeAttribute link=regexp:.*Senior Storeval
click name=chkjob ${Storeval}

where name=chkjob is the attribute for the check box

when I run the above case selenium selects the first checkbox it encounters . But I want it to select the check box for a link that has text starting with 'senior'.
