Error Handling

[HarishChand]

SUPPOSE
int rowCounts=es.NumRows

for iRow 1 rowCounts
es.GetCell(searchJobId 1 iRow)
if CellCheck(searchJobId)
Htm el_setJobId=htm("INPUT" "txtJobNumber" "" win("Vendor Solution - Windows Internet Explorer" "IEFrame") "2" 3 0x221)
el_setJobId.SetText(searchJobId)
out "JobId set focus"

My next step is to click submit button
Htm CmdFind=htm("INPUT" "btnFind" "" win("Vendor Solution - Windows Internet Explorer" "IEFrame") "2" 8 0x121)
CmdFind.Click

and When Invalid data is enter then Button not work. Macro cannot go forward next step and generate error "object not found"
How I can solve this problem.
........

I want to say, If searchJobId is Invalid. Then macro is running continue and go to for loop

Problem is when data is Invalid macro "object not found"
