Help me fix combining ISE and XPS codes

[j hemangini]

I am using EDK9.2i and ISE9.2i. I made a project in EDK and then export it to ISE. When i opened this projet in ISE and compiled it i got the following error.

/************************************************************/
ERROR:LIT:411 - IOBUFDS symbol

Actually i have developed a simple code(VHDL) for LED on off controlled by switch using ISE and have configured the hardware using XPS . So now i want to add both of them . How can i do this.
And what is the problem for this error. Please tell me.
Thankyou.

xps in ise

ERROR:LIT:411 - IOBUFDS symbol/.../does not have IOSTANDARD specified

looks like you use an I/O cell or buffer but you did not tell the tool an I/O level
- 3.3V, 2.5, lvds, sstl etc.
add the information and should be ok;
