?>

in this at the function named GetShippingDeta ils( $token )
at the line if ("Sale" == $paymentType) here it is giving error
as Parse error: syntax error, unexpected T_IF

[Dormilich]

line 213 is missing a semi-colon.

EDIT: please post in future not the whole code, the GetShippingDeta ils() function would have been enough.

rule of thumb: "unexpected T_*" means in 99% of the cases, that there is a basic syntax error like: missing semi-colon, missing (concatenation) operator, etc.

[sidhx]

error shows in line no. 214

[Dormilich]

did you correct what I pointed out?

[sidhx]

yes Dormilich its in the line no. 214

[Dormilich]

did you correct what I pointed out?!

[sidhx]

ok i corrected it but now i have error in Parse error: syntax error, unexpected T_STRING in on line 382

[Dormilich]

correct, that whole comment is not a comment. compare it to the other comments and make the necessary adjustments.

[Markus]

You are not writing BASIC here. Comment syntax is different.

[sidhx]

NOW I am getting this SetExpressCheck outDetails API call failed. Error Message: Invalid amountError Code: 4

[Dormilich]

curl_init()
