transfer data code from pc to omron plc

please help,
at first manual say if you want to send data to plc yse this code "sysmac_cs11.dm(0)=&h1234"
but i want to send data from text so i tried use this code
"sysmac_cs11.dm(0)=&htext1.text"
but vb not accept this code
so i made another code
"sysmac_cs11.dm(0)=hex(1234)"
but the data which sending not correct ,
