iMacro help with checkboxes

What i need is help with this coding for imacro. I need to create a macro which checks off the first two boxes available to check off and to stop checking off after checking off two. the check boxes are named as follows,

VERSION BUILD=1011 RECORDER=CR
URL GOTO=https://cypresslakecc.clubhouseonline-e3.com/TeeTimes/TeeSheet.aspx
FRAME F=1
TAG POS=1 TYPE=INPUT:CHECKBOX FORM=ID:form1 ATTR=* CONTENT=YES
TAG POS=2 TYPE=INPUT:CHECKBOX FORM=ID:form1 ATTR=* CONTENT=YES
TAG POS=3 TYPE=INPUT:CHECKBOX FORM=ID:form1 ATTR=* CONTENT=YES
TAG POS=4 TYPE=INPUT:CHECKBOX FORM=ID:form1 ATTR=* CONTENT=YES
TAG POS=5 TYPE=INPUT:CHECKBOX FORM=ID:form1 ATTR=* CONTENT=YES
TAG POS=6 TYPE=INPUT:CHECKBOX FORM=ID:form1 ATTR=* CONTENT=YES
TAG POS=7 TYPE=INPUT:CHECKBOX FORM=ID:form1 ATTR=* CONTENT=YES


Sometimes not all the checkboxes are available like in the photo only the first and the third are available. I would want those checkboxes to be checked and not any others down the page. Only the first two that are available and then stop there.
