two columns and trigger

[saumyashah90]

i have two columns

ColA and ColB

223          225

224          223

225          224

these have same values.

So o have made something like...when a person click on 223 in ColA, automatically 223 will get selected in ColB

using a variable.

and same if a person select on 224 on ColB  automatically 224 from colA gets selected.

now i want to deselect both if any one of it gets deselected

for example if i deselect 225 in ColB , selection should get removed from ColA also

Also i should be able to click on multiple fields together
